Below find proposed time zone package changes; the executive summary:
* Makefile Change LOCALTIME default from "Factory" to "GMT";
do not compile "factory" file
(but keep it in the distribution).
* Theory Remove reference to "Factory" zone.
* australasia Change end of DST in Samoa in 2011 from
2011-04-03 0:00 to 2011-04-03 1:00
(thanks to Raymond Hughes for a reference).
* localtime.c Initialize ttinfo structures filled by tzparse
(thanks to Ravindra for reporting a valgrind warning).
* zic.c Fix generation of POSIX strings for zones with
rules using "weekday<=n" forms of dates
(thanks to Lei Liu for finding the problem).
Also, limit output for non-POSIX-specificable zones
defined to follow the same rules every year.
(Note that no zones of either of the above types
appear in the distribution; these changes cater to
add-on zones).
If no problems are found, 2010n will appear on 2010-10-25.

According to some news Brazilian state of Goiás may abolish DST:
"The Energy and Mines Commission of the House of Representatives
approved a Legislative Decree that suspends daylight saving time in Goiás."
http://www.infomoney.com.br/minhas-financas/consumo/noticia/7061178/comissa…
Also, ".... this year the federal government even considered not
implementing daylight saving time, but left the decision to 2018."

[PATCH] Support building zic.exe and zdump.exe natively on Windows with Visual Studio nmake.
by Manuela Friedrich 28 Oct '18
by Manuela Friedrich 28 Oct '18
28 Oct '18
Provide getopt() implementation for Windows as per ftp://ftp.es.ele.tue.nl/pub/users/jos/poster/getopt.c
In localtime.c use native localtime(), gmtime(), ctime() and mktime().
Also use int or __int64 respectively for ssize_t type and check for Windows drive letters in tzloadbody().
In private.h and zdump.c define strotimax depending on Visual Studio version.
It needs to be strtol for up to VS 2010 and stroll for higher versions.
In zdump.c need prototype for gmtime_r() to suffice return type requirements.
Also use __time64_t variables on Windows instead of time_t.
In main() variable declarations had to be moved to the top to avoid compile errors.
In zic.c dolink() need to have an extra mkdirs() call for Windows as we don't have link support here and the previous mkdirs() calls wouldn't have been called therefore.
Also itsdir() needs separate Windows part to check for directory flag as the namesslashdot Linux alternative alway returns directory on Windows.
Add nmake specific Makefile.nmake based on existing Makefile.
It uses different object, library and executable extensions, sets CC and CFLAGS for 64 and 32bit Windows build.
Target root has been added to build zdump and zic.
Version and version.h rules were changed to batch.

+# #
+# # To omit or support the external variable "tzname", add one of:

+# If you want functions that were inspired by early versions of X3J11's work,

+# "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.

Hi,
while parsing the data i found the issue in rule Europe/Dublin
Negative DST.. Previous version or not in any other file there is no
negative dst.
DST either start and end .

This is intended to provide a way to support both clients that require
data to have only positive DST offsets, and clients that do not have
this restriction.
* Makefile (XDST, SDST): New macros.
(TZDATA_ZI_DEPS): Add zidst.awk.
(DSTDATA_ZI_DEPS): New macro.
(all): Depend on fulldata.zi and pdstdata.zi.
(fulldata.zi pdstdata.zi): New rule.
(tzdata.zi): Use $(XDST)data.zi instead of reading original source.
(check_zishrink): Check zidst.awk, too.
(clean): Remove all *.zi files, not just tzdata.zi.
* NEWS, europe: Mention this.
* zidst.awk: New file.

Unreleased, experimental changes
+ Briefly:
+ Support zi parsers that mishandle negative DST offsets
+
+ Changes to build procedure
+
+ The new XDST macro in the Makefile lets the installer choose
+ XDST=full, which allows arbitrary DST offsets in the data, or
+ XDST=pdst, which allows only positive DST offsets. Choosing
+ XDST=full is arguably more correct for Ireland, which observes
+ Irish Standard Time (IST, UTC+01) in summer and GMT (UTC) in
+ winter. Choosing XDST=pdst is better for zoneinfo parsers that do
+ not work well with negative DST offsets, notably OpenJDK+CLDR.
+ On platforms using tzcode or similar APIs, XDST should not affect
+ any behavior other than that depending on the tm_isdst flag.
+
+ For now this change does not affect client-visible behavior by
+ default, as the Makefile defaults to XDST=pdst and uncommented
+ parts of the data source files contain only pdst-format data.
+ After a bit of time for testing, XDST=full and full-format source
+ files are planned to become the default, so that parsers that
+ support negative DST offsets can get full data without changing
+ their build procedures. Parsers requiring positive DST offsets
+ should use the new file pdstdata.zi instead of tzdata.zi or the
+ source files 'africa' etc.: pdstdata.zi is pdst-compatible, it is
+ automatically built from the data source files, and it will
+ continue to be pdst-compatible regardless of XDST. To get
+ full-format data now, use the new file fulldata.zi, which will
+ continue to be full-format regardless of XDST. To get the format
+ selected by XDST, use tzdata.zi.
+
Changes to code
The code is a bit more portable to MS-Windows. (Thanks to Manuela
