Problems with the Debian approach are discussed in 53# the commentary for the right_posix rule (below). 54 55# Destination directory, which can be used for staging. 56# 'make DESTDIR=/stage install' installs under /stage (e.g., to 57# /stage/etc/localtime instead of to /etc/localtime). Files under 58# /stage are not intended to work as-is, but can be copied by hand to 59# the root directory later.

If you want both sets of data available, with leap seconds counted 113# normally, use 114# REDO= right_posix 115# below. POSIX mandates that leap seconds not be counted; for compatibility 116# with it, use "posix_only" or "posix_right".

This arranges for the functions 279# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 280# "posix2time", and "time2posix" to be added to the time conversion library. 281# "tzsetwall" is like "tzset" except that it arranges for local wall clock 282# time (rather than the time specified in the TZ environment variable) 283# to be used. 284# "offtime" is like "gmtime" except that it accepts a second (long) argument 285# that gives an offset to add to the time_t when converting it. 286# "timelocal" is equivalent to "mktime". 287# "timegm" is like "timelocal" except that it turns a struct tm into 288# a time_t using UT (rather than local time as "timelocal" does). 289# "timeoff" is like "timegm" except that it accepts a second (long) argument 290# that gives an offset to use when converting to a time_t. 291# "posix2time" and "time2posix" are described in an included manual page. 292# X3J11's work does not describe any of these functions. 293# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 294# These functions may well disappear in future releases of the time 295# conversion package. 296# 297# If you don't want functions that were inspired by NetBSD, add 298# -DNETBSD_INSPIRED=0 299# to the end of the "CFLAGS=" line. Otherwise, the functions 300# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 301# time library, and if STD_INSPIRED is also defined the functions 302# "posix2time_z" and "time2posix_z" are added as well. 303# The functions ending in "_z" (or "_rz") are like their unsuffixed 304# (or suffixed-by-"_r") counterparts, except with an extra first 305# argument of opaque type timezone_t that specifies the time zone. 306# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 307# 308# If you want to allocate state structures in localtime, add 309# -DALL_STATE 310# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 311# 312# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 313# out by the National Institute of Standards and Technology 314# which claims to test C and Posix conformance.
