1# Make and install tzdb code and data. 2 3# This file is in the public domain, so clarified as of 4# 2009-05-17 by Arthur David Olson. 5 6# Package name for the code distribution. 7PACKAGE= tzcode 8 9# Version number for the distribution, overridden in the 'tarballs' rule below. 10VERSION= unknown 11 12# Email address for bug reports. 13BUGEMAIL= tz@iana.org 14 15# DATAFORM selects the data format. 16# Available formats represent essentially the same data, albeit 17# possibly with minor discrepancies that users are not likely to notice. 18# To get new features and the best data right away, use: 19# DATAFORM= vanguard 20# To wait a while before using new features, to give downstream users 21# time to upgrade zic (the default), use: 22# DATAFORM= main 23# To wait even longer for new features, use: 24# DATAFORM= rearguard 25# Rearguard users might also want "ZFLAGS = -b fat"; see below. 26DATAFORM= main 27 28# Change the line below for your timezone (after finding the one you want in 29# one of the $(TDATA) source files, or adding it to a source file). 30# Alternatively, if you discover you've got the wrong timezone, you can just 31# 'zic -l -' to remove it, or 'zic -l rightzone' to change it. 32# Use the command 33# make zonenames 34# to get a list of the values you can use for LOCALTIME. 35 36LOCALTIME= GMT 37 38# The POSIXRULES macro controls interpretation of nonstandard and obsolete 39# POSIX-like TZ settings like TZ='EET-2EEST' that lack DST transition rules. 40# Such a setting uses the rules in a template file to determine 41# "spring forward" and "fall back" days and times; the environment 42# variable itself specifies UT offsets of standard and daylight saving time. 43# 44# If POSIXRULES is '-', no template is installed; this is the default. 45# 46# Any other value for POSIXRULES is obsolete and should not be relied on, as: 47# * It does not work correctly in popular implementations such as GNU/Linux. 48# * It does not work in the tzdb implementation for timestamps after 2037. 49# * It is incompatible with 'zic -b slim' if POSIXRULES specifies transitions 50# at standard time or UT rather than at local time. 51# In short, software should avoid ruleless settings like TZ='EET-2EEST' 52# and so should not depend on the value of POSIXRULES. 53# 54# If, despite the above, you want a template for handling these settings, 55# you can change the line below (after finding the timezone you want in the 56# one of the $(TDATA) source files, or adding it to a source file). 57# Alternatively, if you discover you've got the wrong timezone, you can just 58# 'zic -p -' to remove it, or 'zic -p rightzone' to change it. 59# Use the command 60# make zonenames 61# to get a list of the values you can use for POSIXRULES. 62 63POSIXRULES= - 64 65# Also see TZDEFRULESTRING below, which takes effect only 66# if the time zone files cannot be accessed. 67 68 69# Installation locations. 70# 71# The defaults are suitable for Debian, except that if REDO is 72# posix_right or right_posix then files that Debian puts under 73# /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead 74# put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps, 75# respectively.

If you want both sets of data available, with leap seconds counted 140# normally, use 141# REDO= right_posix 142# below. POSIX mandates that leap seconds not be counted; for compatibility 143# with it, use "posix_only" or "posix_right". Use POSIX time on systems with 144# leap smearing; this can work better than unsmeared "right" time with 145# applications that are not leap second aware, and is closer to unsmeared 146# "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error). 147 148REDO= posix_right 149 150# Whether to put an "Expires" line in the leapseconds file. 151# Use EXPIRES_LINE=1 to put the line in, 0 to omit it. 152# The EXPIRES_LINE value matters only if REDO's value contains "right". 153# If you change EXPIRES_LINE, remove the leapseconds file before running "make". 154# zic's support for the Expires line was introduced in tzdb 2020a, 155# and EXPIRES_LINE defaults to 0 for now so that the leapseconds file 156# can be given to older zic implementations. 157EXPIRES_LINE= 0 158 159# To install data in text form that has all the information of the TZif data, 160# (optionally incorporating leap second information), use 161# TZDATA_TEXT= tzdata.zi leapseconds 162# To install text data without leap second information (e.g., because 163# REDO='posix_only'), use 164# TZDATA_TEXT= tzdata.zi 165# To avoid installing text data, use 166# TZDATA_TEXT= 167 168TZDATA_TEXT= leapseconds tzdata.zi 169 170# For backward-compatibility links for old zone names, use 171# BACKWARD= backward 172# To omit these links, use 173# BACKWARD= 174 175BACKWARD= backward 176 177# If you want out-of-scope and often-wrong data from the file 'backzone', use 178# PACKRATDATA= backzone 179# To omit this data, use 180# PACKRATDATA= 181 182PACKRATDATA= 183 184# The name of a locale using the UTF-8 encoding, used during self-tests. 185# The tests are skipped if the name does not appear to work on this system. 186 187UTF8_LOCALE= en_US.utf8 188 189# Non-default libraries needed to link. 190LDLIBS= 191 192# Add the following to the end of the "CFLAGS=" line as needed to override 193# defaults specified in the source code.

Otherwise, the functions 342# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 343# time library, and if STD_INSPIRED is also defined the functions 344# "posix2time_z" and "time2posix_z" are added as well. 345# The functions ending in "_z" (or "_rz") are like their unsuffixed 346# (or suffixed-by-"_r") counterparts, except with an extra first 347# argument of opaque type timezone_t that specifies the timezone. 348# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 349# 350# If you want to allocate state structures in localtime, add 351# -DALL_STATE 352# to the end of the "CFLAGS=" line.
