# 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:

# 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).
# Alternatively, 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.
# Alternatively, 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".

# 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

# the root directory later. If DESTDIR is empty, 'make install' does
# not stage, but installs directly into production locations.

# 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

# "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).

# -DEPOCH_LOCAL if the 'time' function returns local time not UT
# -DEPOCH_OFFSET=N if the 'time' function returns a value N greater

# -DHAVE_DIRECT_H if mkdir needs <direct.h> (MS-Windows)
# -DHAVE_GENERIC=0 if _Generic does not work
# -DHAVE_GETTEXT if 'gettext' works (e.g., GNU/Linux, FreeBSD, Solaris)
# -DHAVE_INCOMPATIBLE_CTIME_R if your system's time.h declares
# ctime_r and asctime_r incompatibly with the POSIX standard
# (Solaris when _POSIX_PTHREAD_SEMANTICS is not defined).
# -DHAVE_INTTYPES_H if you have a non-C99 compiler with <inttypes.h>
# -DHAVE_LINK=0 if your system lacks a link function
# -DHAVE_LOCALTIME_R=0 if your system lacks a localtime_r function
# -DHAVE_LOCALTIME_RZ=0 if you do not want zdump to use localtime_rz
# localtime_rz can make zdump significantly faster, but is nonstandard.
# -DHAVE_POSIX_DECLS=0 if your system's include files do not declare
# functions like 'link' or variables like 'tzname' required by POSIX
# -DHAVE_SNPRINTF=0 if your system lacks the snprintf function

# -DRESERVE_STD_EXT_IDS if your platform reserves standard identifiers
# with external linkage, e.g., applications cannot define 'localtime'.
# -Dssize_t=long on hosts like MS-Windows that lack ssize_t
# -DSUPPRESS_TZDIR to not prepend TZDIR to file names; this has
# security implications and is not recommended for general use
# -DTHREAD_SAFE to make localtime.c thread-safe, as POSIX requires;
# not needed by the main-program tz code, which is single-threaded.
# Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
# -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t
# This is intended for internal use only; it mangles external names.
# -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
# -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;
# the default is system-supplied, typically "/usr/lib/locale"
# -DTZDEFRULESTRING=\",date/time,date/time\" to default to the specified
# DST transitions if the time zone files cannot be accessed
# -DUNINIT_TRAP if reading uninitialized storage can cause problems
# other than simply getting garbage data
# -DUSE_LTZ=0 to build zdump with the system time zone library
# Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below.

# 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:
# # -DHAVE_TZNAME=0
# # -DHAVE_TZNAME=1
# # 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
# # -DUSG_COMPAT=0
# # -DUSG_COMPAT=1
# # 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
# # -DALTZONE
# # 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
# -DSTD_INSPIRED
# 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
# -DNETBSD_INSPIRED=0
# 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
# -DALL_STATE
# 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
# -DPCTS
# 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.
