# This file is in the public domain, so clarified as of
# 2009-05-17 by Arthur David Olson.
# Package name for the code distribution.
PACKAGE= tzcode
# Version number for the distribution, overridden in the 'tarballs' rule below.
VERSION= unknown
# Email address for bug reports.
# Choose source data features. To get new features right away, use:
# DATAFORM= vanguard
# To wait a while before using new features, to give downstream users
# time to upgrade zic (the default), use:
# DATAFORM= main
# To wait even longer for new features, use:
# DATAFORM= rearguard
# Change the line below for your time zone (after finding the zone you want in
# the time zone files, or adding it to a time zone file).
# Alternately, if you discover you've got the wrong time zone, you can just
# zic -l rightzone
# to correct things.
# Use the command
# make zonenames
# to get a list of the values you can use for LOCALTIME.
# If you want something other than Eastern United States time as a template
# for handling POSIX-style time zone environment variables,
# change the line below (after finding the zone you want in the
# time zone files, or adding it to a time zone file).
# When a POSIX-style environment variable is handled, the rules in the
# template file are used to determine "spring forward" and "fall back" days and
# times; the environment variable itself specifies UT offsets of standard and
# daylight saving time.
# Alternately, if you discover you've got the wrong time zone, you can just
# zic -p rightzone
# to correct things.
# Use the command
# make zonenames
# to get a list of the values you can use for POSIXRULES.
# If you want POSIX compatibility, use "America/New_York".
POSIXRULES= America/New_York
# Also see TZDEFRULESTRING below, which takes effect only
# if the time zone files cannot be accessed.
# Installation locations.
# The defaults are suitable for Debian, except that if REDO is
# posix_right or right_posix then files that Debian puts under
# /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead
# put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps,
# respectively. Problems with the Debian approach are discussed in
# the commentary for the right_posix rule (below).
# Destination directory, which can be used for staging.
# 'make DESTDIR=/stage install' installs under /stage (e.g., to
# /stage/etc/localtime instead of to /etc/localtime). Files under
# /stage are not intended to work as-is, but can be copied by hand to
# the root directory later. If DESTDIR is empty, 'make install' does
# not stage, but installs directly into production locations.
# Everything is installed into subdirectories of TOPDIR, and used there.
# TOPDIR should be empty (meaning the root directory),
# or a directory name that does not end in "/".
# TOPDIR should be empty or an absolute name unless you're just testing.
# The default local time zone is taken from the file TZDEFAULT.
TZDEFAULT = $(TOPDIR)/etc/localtime
# The subdirectory containing installed program and data files, and
# likewise for installed files that can be shared among architectures.
# These should be relative file names.
USRDIR = usr
# "Compiled" time zone information is placed in the "TZDIR" directory
# (and subdirectories).
# TZDIR_BASENAME should not contain "/" and should not be ".", ".." or empty.

# The "zdump" command goes in:
# The "zic" command goes in:
# Manual pages go in subdirectories of. . .

# If you want only POSIX time, with time values interpreted as

# below. If you want only "right" time, with values interpreted
# as seconds since the epoch (counting leap seconds), use
# REDO= right_only
# below. If you want both sets of data available, with leap seconds not
# counted normally, use
# REDO= posix_right
# below. If you want both sets of data available, with leap seconds counted
# normally, use
# REDO= right_posix
# below. POSIX mandates that leap seconds not be counted; for compatibility
# with it, use "posix_only" or "posix_right". Use POSIX time on systems with
# leap smearing; this can work better than unsmeared "right" time with
# applications that are not leap second aware, and is closer to unsmeared
# "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).
REDO= posix_right
# To install data in text form that has all the information of the binary data,

# If your system has a "GMT offset" field in its "struct tm"s
# (or if you decide to add such a field in your system's "time.h" file),
# add the name to a define such as
# -DTM_GMTOFF=tm_gmtoff
# to the end of the "CFLAGS=" line. If not defined, the code attempts to
# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
# Similarly, if your system has a "zone abbreviation" field, define
# -DTM_ZONE=tm_zone
# and define NO_TM_ZONE to suppress any guessing. These two fields are not
# required by POSIX, but are widely available on GNU/Linux and BSD systems.
# The next batch of options control support for external variables
# exported by tzcode. In practice these variables are less useful
# than TM_GMTOFF and TM_ZONE. However, most of them are standardized.
# #
# # To omit or support the external variable "tzname", add one of:
# # to the "CFLAGS=" line. "tzname" is required by POSIX 1988 and later.
# # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
# # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
# # crashes when combined with some platforms' standard libraries,
# # presumably due to memory allocation issues.
# #
# # To omit or support the external variables "timezone" and "daylight", add
# # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
# # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
# # If not defined, the code attempts to guess USG_COMPAT from other macros.
# #
# # To support the external variable "altzone", add
# # to the end of the "CFLAGS=" line; although "altzone" appeared in
# # System V Release 3.1 it has not been standardized.
# If you want functions that were inspired by early versions of X3J11's work,
# add
# to the end of the "CFLAGS=" line. This arranges for the functions
# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
# "posix2time", and "time2posix" to be added to the time conversion library.
# "tzsetwall" is like "tzset" except that it arranges for local wall clock
# time (rather than the time specified in the TZ environment variable)
# to be used.
# "offtime" is like "gmtime" except that it accepts a second (long) argument
# that gives an offset to add to the time_t when converting it.
# "timelocal" is equivalent to "mktime".
# "timegm" is like "timelocal" except that it turns a struct tm into
# a time_t using UT (rather than local time as "timelocal" does).
# "timeoff" is like "timegm" except that it accepts a second (long) argument
# that gives an offset to use when converting to a time_t.
# "posix2time" and "time2posix" are described in an included manual page.
# X3J11's work does not describe any of these functions.
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
# These functions may well disappear in future releases of the time
# conversion package.
# If you don't want functions that were inspired by NetBSD, add
# to the end of the "CFLAGS=" line. Otherwise, the functions
# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
# time library, and if STD_INSPIRED is also defined the functions
# "posix2time_z" and "time2posix_z" are added as well.
# The functions ending in "_z" (or "_rz") are like their unsuffixed
# (or suffixed-by-"_r") counterparts, except with an extra first
# argument of opaque type timezone_t that specifies the time zone.
# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
# If you want to allocate state structures in localtime, add
# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
# out by the National Institute of Standards and Technology
# which claims to test C and Posix conformance. If you want to pass PCTS, add
# to the end of the "CFLAGS=" line.
# If you want strict compliance with XPG4 as of 1994-04-09, add
# -DXPG4_1994_04_09
# to the end of the "CFLAGS=" line. This causes "strftime" to always return
# 53 as a week number (rather than 52 or 53) for January days before
# January's first Monday when a "%V" format is used and January 1
# falls on a Friday, Saturday, or Sunday.
