tzcode-native: updatet to 2018e
Changes to build procedure
The command 'make tarballs' now also builds the tarball
tzdataVERSION-rearguard.tar.gz, which is like tzdataVERSION.tar.gz
except that it uses rearguard format intended for trailing-edge
data parsers.
Changes to data format and to code
The SAVE column of Rule and Zone lines can now have an 's' or 'd'
suffix, which specifies whether the adjusted time is standard time
or daylight saving time. If no suffix is given, daylight saving
time is used if and only if the SAVE column is nonzero; this is
the longstanding behavior. Although this new feature is not used
in tzdata, it could be used to specify the legal time in Namibia
1994-2017, as opposed to the popular time (see below).
Changes to past time stamps
From 1994 through 2017 Namibia observed DST in winter, not summer.
That is, it used negative DST, as Ireland still does. This change
does not affect UTC offsets; it affects only the tm_isdst flag and
the abbreviation used during summer, which is now CAT, not WAST.
Although (as noted by Michael Deckers) summer and winter time were
both simply called "standard time" in Namibian law, in common
practice winter time was considered to be DST (as noted by Stephen
Colebourne). The full effect of this change is only in vanguard
format; in rearguard and main format, the tm_isdst flag is still
zero in winter and nonzero in summer.
In 1946/7 Czechoslovakia also observed negative DST in winter.
The full effect of this change is only in vanguard format; in
rearguard and main formats, it is modeled as plain GMT without
daylight saving. Also, the dates of some 1944/5 DST transitions
in Czechoslovakia have been changed.
