(Thanks to Michael 33309568Sglebius Deckers.) 34309568Sglebius 35309568Sglebius Second, rules for daylight saving in Italy were changed to agree 36309568Sglebius with Italy's National Institute of Metrological Research (INRiM) 37309568Sglebius except for 1944, as follows (thanks to Pierpaolo Bernardi, Brian 38309568Sglebius Inglis, and Michael Deckers): 39309568Sglebius 40309568Sglebius The 1916-06-03 transition was at 24:00, not 00:00. 41309568Sglebius 42309568Sglebius The 1916-10-01, 1919-10-05, and 1920-09-19 transitions were at 43309568Sglebius 00:00, not 01:00. 44309568Sglebius 45309568Sglebius The 1917-09-30 and 1918-10-06 transitions were at 24:00, not 46309568Sglebius 01:00. 47309568Sglebius 48309568Sglebius The 1944-09-17 transition was at 03:00, not 01:00. This 49309568Sglebius particular change is taken from Italian law as INRiM's table, 50309568Sglebius (which says 02:00) appears to have a typo here. Also, keep the 51309568Sglebius 1944-04-03 transition for Europe/Rome, as Rome was controlled by 52309568Sglebius Germany then. 53309568Sglebius 54309568Sglebius The 1967-1970 and 1972-1974 fallback transitions were at 01:00, 55309568Sglebius not 00:00. 56309568Sglebius 57309568Sglebius Changes to code 58309568Sglebius 59309568Sglebius The code should now be buildable on AmigaOS merely by setting the 60309568Sglebius appropriate Makefile variables.

This fixes a bug with 180309568Sglebius Africa/Casablanca and Africa/El_Aaiun in some year-2037 time 181309568Sglebius stamps on the reference platform. (Thanks to Alexander Belopolsky 182309568Sglebius for reporting the bug and suggesting a way forward.) 183309568Sglebius 184309568Sglebius If the installed localtime and/or posixrules files are symbolic 185309568Sglebius links, zic now keeps them symbolic links when updating them, for 186309568Sglebius compatibility with platforms like OpenSUSE where other programs 187309568Sglebius configure these files as symlinks. 188309568Sglebius 189309568Sglebius zic now avoids hard linking to symbolic links, avoids some 190309568Sglebius unnecessary mkdir and stat system calls, and uses shorter file 191309568Sglebius names internally. 192309568Sglebius 193309568Sglebius zdump has a new -i option to generate transitions in a 194309568Sglebius more-compact but still human-readable format. This option is 195309568Sglebius experimental, and the output format may change in future versions. 196309568Sglebius (Thanks to Jon Skeet for suggesting that an option was needed, 197309568Sglebius and thanks to Tim Parenti and Chris Rovick for further comments.) 198309568Sglebius 199309568Sglebius Changes to build procedure 200309568Sglebius 201309568Sglebius An experimental distribution format is available, in addition 202309568Sglebius to the traditional format which will continue to be distributed. 203309568Sglebius The new format is a tarball tzdb-VERSION.tar.lz with signature 204309568Sglebius file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory 205309568Sglebius tzdb-VERSION containing the code and data of the traditional 206309568Sglebius two-tarball format, along with extra data that may be useful. 207309568Sglebius (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others 208309568Sglebius for comments about the experimental format.) 209309568Sglebius 210309568Sglebius The release version number is now more accurate in the usual case 211309568Sglebius where releases are built from a Git repository. For example, if 212309568Sglebius 23 commits and some working-file changes have been made since 213309568Sglebius release 2016g, the version number is now something like 214309568Sglebius '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. 215309568Sglebius Official releases uses the same version number format as before, 216309568Sglebius e.g., '2016g'. To support the more-accurate version number, its 217309568Sglebius specification has moved from a line in the Makefile to a new 218309568Sglebius source file 'version'. 219309568Sglebius 220309568Sglebius The experimental distribution contains a file to2050.tzs that 221309568Sglebius contains what should be the output of 'zdump -i -c 2050' on 222309568Sglebius primary zones. If this file is available, 'make check' now checks 223309568Sglebius that zdump generates this output. 224309568Sglebius 225309568Sglebius 'make check_web' now works on Fedora-like distributions. 226309568Sglebius 227309568Sglebius Changes to documentation and commentary 228309568Sglebius 229309568Sglebius tzfile.5 now documents the new restriction on POSIX TZ-like 230309568Sglebius strings that is now implemented by zic. 231309568Sglebius 232309568Sglebius Comments now cite URLs for some 1917-1921 Russian DST decrees. 233309568Sglebius (Thanks to Alexander Belopolsky.) 234309568Sglebius 235309568Sglebius tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J 236309568Sglebius (thanks to Meno Hochschild) and ThreeTen-Extra, and its 237309568Sglebius description of Java 8 has been brought up to date (thanks to 238309568Sglebius Stephen Colebourne).

The new file is not recommended 987309568Sglebius for ordinary use and its entries are not installed by default. 988309568Sglebius (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and 989309568Sglebius Isle of Man entries.) 990309568Sglebius 991309568Sglebius Some more zones have been turned into links, when they differed 992309568Sglebius from existing zones only for older time stamps. As usual, 993309568Sglebius these changes affect UTC offsets in pre-1970 time stamps only. 994309568Sglebius Their old contents have been moved to the 'backzone' file. 995309568Sglebius The affected zones are: Africa/Bangui, Africa/Brazzaville, 996309568Sglebius Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, 997309568Sglebius Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. 998309568Sglebius 999309568Sglebius Changes affecting code 1000309568Sglebius 1001309568Sglebius Unless NETBSD_INSPIRED is defined to 0, the tz library now 1002309568Sglebius supplies functions for creating and using objects that represent 1003309568Sglebius time zones. The new functions are tzalloc, tzfree, localtime_rz, 1004309568Sglebius mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and 1005309568Sglebius time2posix_z. They are intended for performance: for example, 1006309568Sglebius localtime_rz (unlike localtime_r) is trivially thread-safe without 1007309568Sglebius locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired 1008309568Sglebius functions, and to Alan Barrett and Jonathan Lennox for helping to 1009309568Sglebius debug the change.) 1010309568Sglebius 1011309568Sglebius zdump now builds with the tz library unless USE_LTZ is defined to 0, 1012309568Sglebius This lets zdump use tz features even if the system library lacks them. 1013309568Sglebius To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 1014309568Sglebius TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. 1015309568Sglebius 1016309568Sglebius zdump now uses localtime_rz if available, as it's significantly faster, 1017309568Sglebius and it can help zdump better diagnose invalid time zone names. 1018309568Sglebius Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ 1019309568Sglebius defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is 1020309568Sglebius not available, zdump now uses localtime_r and tzset if available, 1021309568Sglebius as this is a bit cleaner and faster than plain localtime. Compile 1022309568Sglebius with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system 1023309568Sglebius lacks these two functions. 1024309568Sglebius 1025309568Sglebius If THREAD_SAFE is defined to 1, the tz library is now thread-safe. 1026309568Sglebius Although not needed for tz's own applications, which are single-threaded, 1027309568Sglebius this supports POSIX better if the tz library is used in multithreaded apps. 1028309568Sglebius 1029309568Sglebius Some crashes have been fixed when zdump or the tz library is given 1030309568Sglebius invalid or outlandish input. 1031309568Sglebius 1032309568Sglebius The tz library no longer mishandles leap seconds on platforms with 1033309568Sglebius unsigned time_t in time zones that lack ordinary transitions after 1970. 1034309568Sglebius 1035309568Sglebius The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not 1036309568Sglebius already defined, to make it easier to configure on common platforms. 1037309568Sglebius Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. 1038309568Sglebius 1039309568Sglebius Unless the new macro UNINIT_TRAP is defined to 1, the tz code now 1040309568Sglebius assumes that reading uninitialized memory yields garbage values 1041309568Sglebius but does not cause other problems such as traps. 1042309568Sglebius 1043309568Sglebius If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now 1044309568Sglebius more likely to guess right for ambiguous time stamps near 1045309568Sglebius transitions where tm_isdst does not change. 1046309568Sglebius 1047309568Sglebius If HAVE_STRFTIME_L is defined to 1, the tz library now defines 1048309568Sglebius strftime_l for compatibility with recent versions of POSIX. 1049309568Sglebius Only the C locale is supported, though. HAVE_STRFTIME_L defaults 1050309568Sglebius to 1 on recent POSIX versions, and to 0 otherwise. 1051309568Sglebius 1052309568Sglebius tzselect -c now uses a hybrid distance measure that works better 1053309568Sglebius in Africa. (Thanks to Alan Barrett for noting the problem.) 1054309568Sglebius 1055309568Sglebius The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, 1056309568Sglebius or when time_tz is defined. 1057309568Sglebius 1058309568Sglebius When HAVE_UTMPX_H is set the 'date' command now builds on systems 1059309568Sglebius whose <utmpx.h> file does not define WTMPX_FILE, and when setting 1060309568Sglebius the date it updates the wtmpx file if _PATH_WTMPX is defined. 1061309568Sglebius This affects GNU/Linux and similar systems. 1062309568Sglebius 1063309568Sglebius For easier maintenance later, some C code has been simplified, 1064309568Sglebius some lint has been removed, and the code has been tweaked so that 1065309568Sglebius plain 'make' is more likely to work. 1066309568Sglebius 1067309568Sglebius The C type 'bool' is now used for boolean values, instead of 'int'. 1068309568Sglebius 1069309568Sglebius The long-obsolete LOCALE_HOME code has been removed. 1070309568Sglebius 1071309568Sglebius The long-obsolete 'gtime' function has been removed. 1072309568Sglebius 1073309568Sglebius Changes affecting build procedure 1074309568Sglebius 1075309568Sglebius 'zdump' no longer links in ialloc.o, as it's not needed. 1076309568Sglebius 1077309568Sglebius 'make check_time_t_alternatives' no longer assumes GNU diff. 1078309568Sglebius 1079309568Sglebius Changes affecting distribution tarballs 1080309568Sglebius 1081309568Sglebius The files checktab.awk and zoneinfo2tdf.pl are now distributed in 1082309568Sglebius the tzdata tarball instead of the tzcode tarball, since they help 1083309568Sglebius maintain the data. The NEWS and Theory files are now also 1084309568Sglebius distributed in the tzdata tarball, as they're relevant for data. 1085309568Sglebius (Thanks to Alan Barrett for pointing this out.) Also, the 1086309568Sglebius leapseconds.awk file is no longer distributed in the tzcode 1087309568Sglebius tarball, since it belongs in the tzdata tarball (where 2014f 1088309568Sglebius inadvertently also distributed it). 1089309568Sglebius 1090309568Sglebius Changes affecting documentation and commentary 1091309568Sglebius 1092309568Sglebius A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for 1093309568Sglebius suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms 1094309568Sglebius for debugging it.) 1095309568Sglebius 1096309568Sglebius The man pages have been updated to use function prototypes, 1097309568Sglebius to document thread-safe variants like localtime_r, and to document 1098309568Sglebius the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and 1099309568Sglebius mktime_z. 1100309568Sglebius 1101309568Sglebius The fields in Link lines have been renamed to be more descriptive 1102309568Sglebius and more like the parameters of 'ln'. LINK-FROM has become TARGET, 1103309568Sglebius and LINK-TO has become LINK-NAME. 1104309568Sglebius 1105309568Sglebius tz-link.htm mentions the IETF's tzdist working group; Windows 1106309568Sglebius Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. 1107309568Sglebius 1108309568Sglebius Some broken URLs have been fixed in the commentary. (Thanks to 1109309568Sglebius Lester Caine.) 1110309568Sglebius 1111309568Sglebius Commentary about Philippines DST has been updated, and commentary 1112309568Sglebius on pre-1970 time in India has been added. 1113309568Sglebius 1114309568Sglebius 1115309568SglebiusRelease 2014f - 2014-08-05 17:42:36 -0700 1116309568Sglebius 1117309568Sglebius Changes affecting future time stamps 1118309568Sglebius 1119309568Sglebius Russia will subtract an hour from most of its time zones on 2014-10-26 1120309568Sglebius at 02:00 local time. (Thanks to Alexander Krivenyshev.) 1121309568Sglebius There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky 1122309568Sglebius Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug 1123309568Sglebius (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast 1124309568Sglebius (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic 1125309568Sglebius (Europe/Samara) are not changing their clocks. The changed zones are 1126309568Sglebius Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, 1127309568Sglebius Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, 1128309568Sglebius Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, 1129309568Sglebius Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours 1130309568Sglebius subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, 1131309568Sglebius but not its UTC offset. Two zones are added: Asia/Chita (split 1132309568Sglebius from Asia/Yakutsk, and also with two hours subtracted) and 1133309568Sglebius Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour 1134309568Sglebius subtracted). (Thanks to Tim Parenti for much of the above.) 1135309568Sglebius 1136309568Sglebius Changes affecting time zone abbreviations 1137309568Sglebius 1138309568Sglebius Australian eastern time zone abbreviations are now AEST/AEDT not EST, 1139309568Sglebius and similarly for the other Australian zones. That is, for eastern 1140309568Sglebius standard and daylight saving time the abbreviations are AEST and AEDT 1141309568Sglebius instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT, 1142309568Sglebius and AWST/AWDT are now used instead of the former CST, CWST, and WST. 1143309568Sglebius This change does not affect UTC offsets, only time zone abbreviations. 1144309568Sglebius (Thanks to Rich Tibbett and many others.) 1145309568Sglebius 1146309568Sglebius Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UT +07) 1147309568Sglebius effective 2014-10-26 at 02:00 local time. 1148309568Sglebius 1149309568Sglebius The time zone abbreviation for Xinjiang Time (observed in ��r��mqi) 1150309568Sglebius has been changed from URUT to XJT. (Thanks to Luther Ma.) 1151309568Sglebius 1152309568Sglebius Prefer MSK/MSD for Moscow time in Russia, even in other cities. 1153309568Sglebius Similarly, prefer EET/EEST for eastern European time in Russia. 1154309568Sglebius 1155309568Sglebius Change time zone abbreviations in (western) Samoa to use "ST" and 1156309568Sglebius "DT" suffixes, as this is more likely to match common practice. 1157309568Sglebius Prefix "W" to (western) Samoa time when its standard-time offset 1158309568Sglebius disagrees with that of American Samoa. 1159309568Sglebius 1160309568Sglebius America/Metlakatla now uses PST, not MeST, to abbreviate its time zone. 1161309568Sglebius 1162309568Sglebius Time zone abbreviations have been updated for Japan's two time 1163309568Sglebius zones used 1896-1937. JWST now stands for Western Standard 1164309568Sglebius Time, and JCST for Central Standard Time (formerly this was CJT). 1165309568Sglebius These abbreviations are now used for time in Korea, Taiwan, 1166309568Sglebius and Sakhalin while controlled by Japan. 1167309568Sglebius 1168309568Sglebius Changes affecting past time stamps 1169309568Sglebius 1170309568Sglebius China's five zones have been simplified to two, since the post-1970 1171309568Sglebius differences in the other three seem to have been imaginary. The 1172309568Sglebius zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been 1173309568Sglebius removed; backwards-compatibility links still work, albeit with 1174309568Sglebius different behaviors for time stamps before May 1980. Asia/Urumqi's 1175309568Sglebius 1980 transition to UT +08 has been removed, so that it is now at 1176309568Sglebius +06 and not +08. (Thanks to Luther Ma and to Alois Treindl; 1177309568Sglebius Treindl sent helpful translations of two papers by Guo Qingsheng.) 1178309568Sglebius 1179309568Sglebius Some zones have been turned into links, when they differed from existing 1180309568Sglebius zones only for older UTC offsets where data entries were likely invented. 1181309568Sglebius These changes affect UTC offsets in pre-1970 time stamps only. This is 1182309568Sglebius similar to the change in release 2013e, except this time for western 1183309568Sglebius Africa. The affected zones are: Africa/Bamako, Africa/Banjul, 1184309568Sglebius Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, 1185309568Sglebius Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and 1186309568Sglebius Atlantic/St_Helena. This also affects the backwards-compatibility 1187309568Sglebius link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, 1188309568Sglebius Tim Parenti, and David Patte for reporting problems in earlier 1189309568Sglebius versions of this change.) 1190309568Sglebius 1191309568Sglebius Asia/Shanghai's pre-standard-time UT offset has been changed from 1192309568Sglebius 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its 1193309568Sglebius transition to standard time has been changed from 1928 to 1901. 1194309568Sglebius 1195309568Sglebius Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, 1196309568Sglebius then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. 1197309568Sglebius In 1946 it observed DST from 05-15 through 09-30; in 1947 1198309568Sglebius from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. 1199309568Sglebius (Thanks to Yu-Cheng Chuang.) 1200309568Sglebius 1201309568Sglebius Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. 1202309568Sglebius 1203309568Sglebius Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not 1204309568Sglebius 10-03 at 00:00. (Thanks to Konstantin Hypp��nen.) 1205309568Sglebius 1206309568Sglebius Pacific/Pago_Pago has been changed from UT -11:30 to -11 for the 1207309568Sglebius period from 1911 to 1950. 1208309568Sglebius 1209309568Sglebius Pacific/Chatham has been changed to New Zealand standard time plus 1210309568Sglebius 45 minutes for the period before 1957, reflecting a 1956 remark in 1211309568Sglebius the New Zealand parliament. 1212309568Sglebius 1213309568Sglebius Europe/Budapest has several pre-1946 corrections: in 1918 the transition 1214309568Sglebius out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in 1215309568Sglebius 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 1216309568Sglebius not 04-06 at 02:00; and there was no DST in 1920. 1217309568Sglebius 1218309568Sglebius Africa/Accra is now assumed to have observed DST from 1920 through 1935. 1219309568Sglebius 1220309568Sglebius Time in Russia before 1927 or so has been corrected by a few seconds in 1221309568Sglebius the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, 1222309568Sglebius Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and 1223309568Sglebius Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 1224309568Sglebius point. (Thanks to Vladimir Karpinsky for the Moscow changes.) 1225309568Sglebius 1226309568Sglebius Changes affecting data format 1227309568Sglebius 1228309568Sglebius A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. 1229309568Sglebius The new file's extended format allows multiple country codes per zone. 1230309568Sglebius The older file is still installed but is deprecated; its format is 1231309568Sglebius not changing and it will still be distributed for a while, but new 1232309568Sglebius applications should use the new file. 1233309568Sglebius 1234309568Sglebius The new file format simplifies maintenance of obscure locations. 1235309568Sglebius To test this, it adds coverage for the Crozet Islands and the 1236309568Sglebius Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) 1237309568Sglebius 1238309568Sglebius The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. 1239309568Sglebius It is still ASCII now, but commentary about the switch has been added. 1240309568Sglebius The new file 'zone1970.tab' already uses UTF-8. 1241309568Sglebius 1242309568Sglebius Changes affecting code 1243309568Sglebius 1244309568Sglebius 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE 1245309568Sglebius is defined. (Thanks to Elliott Hughes for reporting the problem.) 1246309568Sglebius 1247309568Sglebius 'zic' no longer mishandles input when ignoring case in locales that 1248309568Sglebius are not compatible with English, e.g., unibyte Turkish locales when 1249309568Sglebius compiled with HAVE_GETTEXT. 1250309568Sglebius 1251309568Sglebius Error diagnostics of 'zic' and 'yearistype' have been reworded so that 1252309568Sglebius they no longer use ASCII '-' as if it were a dash. 1253309568Sglebius 1254309568Sglebius 'zic' now rejects output file names that contain '.' or '..' components. 1255309568Sglebius (Thanks to Tim Parenti for reporting the problem.) 1256309568Sglebius 1257309568Sglebius 'zic -v' now warns about output file names that do not follow 1258309568Sglebius POSIX rules, or that contain a digit or '.'. (Thanks to Arthur 1259309568Sglebius David Olson for starting the ball rolling on this.) 1260309568Sglebius 1261309568Sglebius Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. 1262309568Sglebius 1263309568Sglebius Changes affecting build procedure 1264309568Sglebius 1265309568Sglebius 'zic' no longer links in localtime.o and asctime.o, as they're not needed. 1266309568Sglebius (Thanks to John Cochran.) 1267309568Sglebius 1268309568Sglebius Changes affecting documentation and commentary 1269309568Sglebius 1270309568Sglebius The 'Theory' file documents legacy names, the longstanding 1271309568Sglebius exceptions to the POSIX-inspired file name rules. 1272309568Sglebius 1273309568Sglebius The 'zic' documentation clarifies the role of time types when 1274309568Sglebius interpreting dates.

The timestamps of these and other 1611309568Sglebius dependent files in tarballs are adjusted more consistently. 1612309568Sglebius 1613309568Sglebius Changes affecting documentation and commentary 1614309568Sglebius 1615309568Sglebius The README file is now part of the data tarball as well as the code. 1616309568Sglebius It now states that files are public domain unless otherwise specified. 1617309568Sglebius (Thanks to Andrew Main (Zefram) for asking for clarifications.) 1618309568Sglebius Its details about the 1989 release moved to a place of honor near 1619309568Sglebius the end of NEWS. 1620309568Sglebius 1621309568Sglebius 1622309568SglebiusRelease 2013f - 2013-09-24 23:37:36 -0700 1623309568Sglebius 1624309568Sglebius Changes affecting near-future time stamps 1625309568Sglebius 1626309568Sglebius Tocantins will very likely not observe DST starting this spring. 1627309568Sglebius (Thanks to Steffen Thorsen.) 1628309568Sglebius 1629309568Sglebius Jordan will likely stay at UT +03 indefinitely, and will not fall 1630309568Sglebius back this fall. 1631309568Sglebius 1632309568Sglebius Palestine will fall back at 00:00, not 01:00.

This is required for 'timezone' 1638309568Sglebius by POSIX, and for 'altzone' by common practice, e.g., Solaris 11. 1639309568Sglebius These variables were originally 'long' in the tz code, but were 1640309568Sglebius mistakenly changed to 'time_t' in 1987; nobody reported the 1641309568Sglebius incompatibility until now. The difference matters on x32, where 1642309568Sglebius 'long' is 32 bits and 'time_t' is 64.

For now, guess that 1675309568Sglebius Fiji will continue to spring forward the Sunday before the fourth 1676309568Sglebius Monday in October. 1677309568Sglebius 1678309568Sglebius Changes affecting current and future time zone abbreviations 1679309568Sglebius 1680309568Sglebius Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian 1681309568Sglebius time zone abbreviations since 1932. (Thanks to George Ziegler, 1682309568Sglebius Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and 1683309568Sglebius Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, 1684309568Sglebius Asia/Makassar, and Asia/Pontianak. 1685309568Sglebius 1686309568Sglebius Use ART (UT -03, standard time), rather than WARST (also -03, but 1687309568Sglebius daylight saving time) for San Luis, Argentina since 2009. 1688309568Sglebius 1689309568Sglebius Changes affecting Godth��b time stamps after 2037 if version mismatch 1690309568Sglebius 1691309568Sglebius Allow POSIX-like TZ strings where the transition time's hour can 1692309568Sglebius range from -167 through 167, instead of the POSIX-required 0 1693309568Sglebius through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the 1694309568Sglebius new Fiji rules. This is a more-compact way to represent 1695309568Sglebius far-future time stamps for America/Godthab, America/Santiago, 1696309568Sglebius Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, 1697309568Sglebius Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by 1698309568Sglebius this change. (Derived from a suggestion by Arthur David Olson.) 1699309568Sglebius 1700309568Sglebius Allow POSIX-like TZ strings where daylight saving time is in 1701309568Sglebius effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western 1702309568Sglebius Argentina Summer Time all year. This supports a more-compact way 1703309568Sglebius to represent the 2013d data for America/Argentina/San_Luis. 1704309568Sglebius Because of the change for San Luis noted above this change does not 1705309568Sglebius affect the current data. (Thanks to Andrew Main (Zefram) for 1706309568Sglebius suggestions that improved this change.) 1707309568Sglebius 1708309568Sglebius Where these two TZ changes take effect, there is a minor extension 1709309568Sglebius to the tz file format in that it allows new values for the 1710309568Sglebius embedded TZ-format string, and the tz file format version number 1711309568Sglebius has therefore been increased from 2 to 3 as a precaution. 1712309568Sglebius Version-2-based client code should continue to work as before for 1713309568Sglebius all time stamps before 2038. Existing version-2-based client code 1714309568Sglebius (tzcode, GNU/Linux, Solaris) has been tested on version-3-format 1715309568Sglebius files, and typically works in practice even for time stamps after 1716309568Sglebius 2037; the only known exception is America/Godthab. 1717309568Sglebius 1718309568Sglebius Changes affecting time stamps before 1970 1719309568Sglebius 1720309568Sglebius Pacific/Johnston is now a link to Pacific/Honolulu. This corrects 1721309568Sglebius some errors before 1947. 1722309568Sglebius 1723309568Sglebius Some zones have been turned into links, when they differ from existing 1724309568Sglebius zones only in older data entries that were likely invented or that 1725309568Sglebius differ only in LMT or transitions from LMT. These changes affect 1726309568Sglebius only time stamps before 1943. The affected zones are: 1727309568Sglebius Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, 1728309568Sglebius America/Grenada, America/Guadeloupe, America/Marigot, 1729309568Sglebius America/Montserrat, America/St_Barthelemy, America/St_Kitts, 1730309568Sglebius America/St_Lucia, America/St_Thomas, America/St_Vincent, 1731309568Sglebius America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for 1732309568Sglebius confirming that the old Europe/Vaduz zone was wrong and the new 1733309568Sglebius link is better for WWII-era times.) 1734309568Sglebius 1735309568Sglebius Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects 1736309568Sglebius America/Cayman, America/Jamaica and America/Grand_Turk time stamps 1737309568Sglebius from 1890 to 1912. 1738309568Sglebius 1739309568Sglebius Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. 1740309568Sglebius This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks 1741309568Sglebius to Alois Treindl). 1742309568Sglebius 1743309568Sglebius Change the date of the circa-1850 Zurich transition from 1849-09-12 1744309568Sglebius to 1853-07-16, overriding Shanks with data from Messerli about 1745309568Sglebius postal and telegraph time in Switzerland. 1746309568Sglebius 1747309568Sglebius Changes affecting time zone abbreviations before 1970 1748309568Sglebius 1749309568Sglebius For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, 1750309568Sglebius as Jakarta was called Batavia back then. 1751309568Sglebius 1752309568Sglebius Changes affecting API 1753309568Sglebius 1754309568Sglebius The 'zic' command now outputs a dummy transition when far-future 1755309568Sglebius data can't be summarized using a TZ string, and uses a 402-year 1756309568Sglebius window rather than a 400-year window. For the current data, this 1757309568Sglebius affects only the Asia/Tehran file. It does not affect any of the 1758309568Sglebius time stamps that this file represents, so zdump outputs the same 1759309568Sglebius information as before. (Thanks to Andrew Main (Zefram).) 1760309568Sglebius 1761309568Sglebius The 'date' command has a new '-r' option, which lets you specify 1762309568Sglebius the integer time to display, a la FreeBSD. 1763309568Sglebius 1764309568Sglebius The 'tzselect' command has two new options '-c' and '-n', which lets you 1765309568Sglebius select a zone based on latitude and longitude. 1766309568Sglebius 1767309568Sglebius The 'zic' command's '-v' option now warns about constructs that 1768309568Sglebius require the new version-3 binary file format. (Thanks to Arthur 1769309568Sglebius David Olson for the suggestion.) 1770309568Sglebius 1771309568Sglebius Support for floating-point time_t has been removed. 1772309568Sglebius It was always dicey, and POSIX no longer requires it. 1773309568Sglebius (Thanks to Eric Blake for suggesting to the POSIX committee to 1774309568Sglebius remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy 1775309568Sglebius Heninger, Arthur David Olson, and Alois Treindl, for reporting 1776309568Sglebius bugs and elucidating some of the corners of the old floating-point 1777309568Sglebius implementation.) 1778309568Sglebius 1779309568Sglebius The signatures of 'offtime', 'timeoff', and 'gtime' have been 1780309568Sglebius changed back to the old practice of using 'long' to represent UT 1781309568Sglebius offsets. This had been inadvertently and mistakenly changed to 1782309568Sglebius 'int_fast32_t'. (Thanks to Christos Zoulas.) 1783309568Sglebius 1784309568Sglebius The code avoids undefined behavior on integer overflow in some 1785309568Sglebius more places, including gmtime, localtime, mktime and zdump. 1786309568Sglebius 1787309568Sglebius Changes affecting the zdump utility 1788309568Sglebius 1789309568Sglebius zdump now outputs "UT" when referring to Universal Time, not "UTC". 1790309568Sglebius "UTC" does not make sense for time stamps that predate the introduction 1791309568Sglebius of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen 1792309568Sglebius for clarifying UT vs UTC.) 1793309568Sglebius 1794309568Sglebius Data changes affecting behavior of tzselect and similar programs 1795309568Sglebius 1796309568Sglebius Country code BQ is now called the more-common name "Caribbean Netherlands" 1797309568Sglebius rather than the more-official "Bonaire, St Eustatius & Saba". 1798309568Sglebius 1799309568Sglebius Remove from zone.tab the names America/Montreal, America/Shiprock, 1800309568Sglebius and Antarctica/South_Pole, as they are equivalent to existing 1801309568Sglebius same-country-code zones for post-1970 time stamps. The data entries for 1802309568Sglebius these names are unchanged, so the names continue to work as before. 1803309568Sglebius 1804309568Sglebius Changes affecting code internals 1805309568Sglebius 1806309568Sglebius zic -c now runs way faster on 64-bit hosts when given large numbers. 1807309568Sglebius 1808309568Sglebius zic now uses vfprintf to avoid allocating and freeing some memory. 1809309568Sglebius 1810309568Sglebius tzselect now computes the list of continents from the data, 1811309568Sglebius rather than have it hard-coded. 1812309568Sglebius 1813309568Sglebius Minor changes pacify GCC 4.7.3 and GCC 4.8.1. 1814309568Sglebius 1815309568Sglebius Changes affecting the build procedure 1816309568Sglebius 1817309568Sglebius The 'leapseconds' file is now generated automatically from a 1818309568Sglebius new file 'leap-seconds.list', which is a copy of 1819309568Sglebius <ftp://time.nist.gov/pub/leap-seconds.list>. 1820309568Sglebius A new source file 'leapseconds.awk' implements this. 1821309568Sglebius The goal is simplification of the future maintenance of 'leapseconds'. 1822309568Sglebius 1823309568Sglebius When building the 'posix' or 'right' subdirectories, if the 1824309568Sglebius subdirectory would be a copy of the default subdirectory, it is 1825309568Sglebius now made a symbolic link if that is supported. This saves about 1826309568Sglebius 2 MB of file system space. 1827309568Sglebius 1828309568Sglebius The links America/Shiprock and Antarctica/South_Pole have been 1829309568Sglebius moved to the 'backward' file. This affects only nondefault builds 1830309568Sglebius that omit 'backward'. 1831309568Sglebius 1832309568Sglebius Changes affecting version-control only 1833309568Sglebius 1834309568Sglebius .gitignore now ignores 'date'. 1835309568Sglebius 1836309568Sglebius Changes affecting documentation and commentary 1837309568Sglebius 1838309568Sglebius Changes to the 'tzfile' man page 1839309568Sglebius 1840309568Sglebius It now mentions that the binary file format may be extended in 1841309568Sglebius future versions by appending data. 1842309568Sglebius 1843309568Sglebius It now refers to the 'zdump' and 'zic' man pages. 1844309568Sglebius 1845309568Sglebius Changes to the 'zic' man page 1846309568Sglebius 1847309568Sglebius It lists conditions that elicit a warning with '-v'. 1848309568Sglebius 1849309568Sglebius It says that the behavior is unspecified when duplicate names 1850309568Sglebius are given, or if the source of one link is the target of another. 1851309568Sglebius 1852309568Sglebius Its examples are updated to match the latest data. 1853309568Sglebius 1854309568Sglebius The definition of white space has been clarified slightly. 1855309568Sglebius (Thanks to Michael Deckers.) 1856309568Sglebius 1857309568Sglebius Changes to the 'Theory' file 1858309568Sglebius 1859309568Sglebius There is a new section about the accuracy of the tz database, 1860309568Sglebius describing the many ways that errors can creep in, and 1861309568Sglebius explaining why so many of the pre-1970 time stamps are wrong or 1862309568Sglebius misleading (thanks to Steve Allen, Lester Caine, and Garrett 1863309568Sglebius Wollman for discussions that contributed to this). 1864309568Sglebius 1865309568Sglebius The 'Theory' file describes LMT better (this follows a 1866309568Sglebius suggestion by Guy Harris). 1867309568Sglebius 1868309568Sglebius It refers to the 2013 edition of POSIX rather than the 2004 edition. 1869309568Sglebius 1870309568Sglebius It's mentioned that excluding 'backward' should not affect the 1871309568Sglebius other data, and it suggests at least one zone.tab name per 1872309568Sglebius inhabited country (thanks to Stephen Colebourne). 1873309568Sglebius 1874309568Sglebius Some longstanding restrictions on names are documented, e.g., 1875309568Sglebius 'America/New_York' precludes 'America/New_York/Bronx'. 1876309568Sglebius 1877309568Sglebius It gives more reasons for the 1970 cutoff. 1878309568Sglebius 1879309568Sglebius It now mentions which time_t variants are supported, such as 1880309568Sglebius signed integer time_t. (Thanks to Paul Goyette for reporting 1881309568Sglebius typos in an experimental version of this change.) 1882309568Sglebius 1883309568Sglebius (Thanks to Philip Newton for correcting typos in these changes.) 1884309568Sglebius 1885309568Sglebius Documentation and commentary is more careful to distinguish UT in 1886309568Sglebius general from UTC in particular.

And third, the 2225309568Sglebius end date for Fiji's summer time this summer was moved forward from the 2226309568Sglebius earlier planned Feb 26, to Jan 22. 2227309568Sglebius 2228309568Sglebius Apart from that, Moldova (MD) returns to a single entry in zone.tab 2229309568Sglebius (and the incorrect syntax that was in the 2011m version of that file 2230309568Sglebius is so fixed - it would have been fixed in a different way had this 2231309568Sglebius change not happened - that's the "missing" sccs version id). 2232309568Sglebius 2233309568Sglebius 2234309568SglebiusRelease data2011m - 2011-10-24 21:42:16 +0700 2235309568Sglebius 2236309568Sglebius In particular, the typos in comments in the data (2011-11-17 should have 2237309568Sglebius been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that 2238309568Sglebius Tim Parenti noted) have been fixed, and the change for Ukraine has been 2239309568Sglebius made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to 2240309568Sglebius Tim Parenti, and also Denys Gavrysh) 2241309568Sglebius 2242309568Sglebius In addition, I added Europe/Tiraspol to zone.tab. 2243309568Sglebius 2244309568Sglebius This time, all the files have new version numbers...

However, some releases (e.g., 3764309568Sglebiuscode2010a, data2012c) consist of just one or the other tarball, and a 3765309568Sglebiusfew (e.g., code2012c-data2012d) have tarballs with mixed version 3766309568Sglebiusnumbers. Recent releases also come in an experimental format 3767309568Sglebiusconsisting of a single tarball tzdb-R.tar.lz with extra data. 3768309568Sglebius 3769309568SglebiusRelease time stamps are taken from the release's commit (for newer, 3770309568SglebiusGit-based releases), from the newest file in the tarball (for older 3771309568Sglebiusreleases, where this info is available) or from the email announcing 3772309568Sglebiusthe release (if all else fails; these are marked with a time zone of 3773309568Sglebius-0000 and an "is missing!" comment). 3774309568Sglebius 3775309568SglebiusEarlier versions of the code and data were not announced on the tz 3776309568Sglebiuslist and are not summarized here. 3777309568Sglebius 3778309568SglebiusThis file is in the public domain. 3779309568Sglebius 3780309568SglebiusLocal Variables: 3781309568Sglebiuscoding: utf-8 3782309568SglebiusEnd: 3783
