The 2018c release of the tz code and data is available. It follows on the 2018a and 2018b releases, which were published but were not announced until now, due to problems discovered late in their release processes. 2018a had a build-failure typo, and 2018a and 2018b both had problems with ICU and Java, downstream packages which do not support a feature (negative DST offsets) used in 2018a and 2018b. The typo has been fixed, and data changes using negative DST offsets have been reverted pending development of a mechanism to export data to platforms lacking support for such data.
Briefly:
São Tomé and Príncipe switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style.
New zic option -t.
Changes to past and future time stamps
São Tomé and Príncipe switched from +00 to +01 on 2018-01-01 at
01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's
first Sunday instead of October's third Sunday. (Thanks to
Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not
Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has
been corrected. The 'backzone' and 'zone.tab' files did not agree
with the 'africa' and 'zone1970.tab' files. (Problem reported by
Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now
BST instead of BOST, to be more consistent with the convention
used for Latvian Summer Time (1918-9) and for British Summer Time.
Changes to build procedure
The default installation locations have been changed to mostly
match Debian circa 2017, instead of being designed as an add-on to
4.3BSD circa 1986. This affects the Makefile macros TOPDIR,
TZDIR, MANDIR, and LIBDIR. New Makefile macros TZDEFAULT, USRDIR,
USRSHAREDIR, BINDIR, ZDUMPDIR, and ZICDIR let installers tailor
locations more precisely. (This responds to suggestions from
Brian Inglis and from Steve Summit.)
The default installation procedure no longer creates the
backward-compatibility link US/Pacific-New, which causes
confusion during user setup (e.g., see Debian bug 815200).
Use 'make BACKWARD="backward pacificnew"' to create the link
anyway, for now. Eventually we plan to remove the link entirely.
tzdata.zi now contains a version-number comment.
(Suggested by Tom Lane.)
The Makefile now quotes values like BACKWARD more carefully when
passing them to the shell. (Problem reported by Zefram.)
Builders no longer need to specify -DHAVE_SNPRINTF on platforms
that have snprintf and use pre-C99 compilers. (Problem reported
by Jon Skeet.)
The build procedure now works around mawk 1.3.3's lack of support
for character class expressions. (Problem reported by Ohyama.)
