News for the tz database
+Release 2018c - 2018-01-22 23:00:44 -0800
+
+ Briefly:
+ Revert Irish changes that relied on negative DST offsets.
+
+ Changes to tm_isdst
+
+ Revert the 2018a change to Europe/Dublin. As before, this change
+ does not affect UT offsets or abbreviations; it affects only
+ whether timestamps are considered to be standard time or
+ daylight-saving time, as expressed in the tm_isdst flag of C's
+ struct tm type. This reversion is intended to be a temporary
+ workaround for problems discovered with downstream uses of
+ releases 2018a and 2018b, which implemented Irish time by using
+ negative DST offsets in the Eire rules of the 'europe' file.
+ Although negative DST offsets have been part of tzcode for many
+ years and are supported by many platforms, they were not
+ documented before 2018a and ICU and OpenJDK do not currently
+ support them. A mechanism to export data to platforms lacking
+ support for negative DST is planned to be developed before the
+ change is reapplied. (Problems reported by Deborah Goldsmith and
+ Stephen Colebourne.)
+
+ 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.)
+
+ Changes to build procedure
+
+ The build procedure now works around mawk 1.3.3's lack of support
+ for character class expressions. (Problem reported by Ohyama.)
+
+
+Release 2018b - 2018-01-17 23:24:48 -0800
+
+ Briefly:
+ Fix a packaging problem in tz2018a, which was missing 'pacificnew'.
+
+ Changes to build procedure
+
+ The distribution now contains the file 'pacificnew' again.
+ This file was inadvertantly omitted in the 2018a distribution.
+ (Problem reported by Matias Fonzo.)
