News for the tz database
Release 2018g - 2018-10-26 22:22:45 -0700
Briefly:
Morocco switches to permanent +01 on 2018-10-27.
Changes to future timestamps
Morocco switches from +00/+01 to permanent +01 effective 2018-10-27,
so its clocks will not fall back on 2018-10-28 as previously scheduled.
(Thanks to Mohamed Essedik Najd and Brian Inglis.)
Changes to code
When generating TZif files with leap seconds, zic no longer uses a
format that trips up older 32-bit clients, fixing a bug introduced
in 2018f. (Reported by Daniel Fischer.) Also, the zic workaround
for QTBUG-53071 now also works for TZif files with leap seconds.
The translator to rearguard format now rewrites the line
"Rule Japan 1948 1951 - Sep Sat>=8 25:00 0 S" to
"Rule Japan 1948 1951 - Sep Sun>=9 1:00 0 S".
This caters to zic before 2007 and to Oracle TZUpdater 2.2.0
and earlier. (Reported by Christos Zoulas.)
Changes to past time zone abbreviations
Change HDT to HWT/HPT for WWII-era abbreviations in Hawaii.
This reverts to 2011h, as the abbreviation change in 2011i was
likely inadvertent.
Changes to documentation
tzfile.5 has new sections on interoperability issues.

#
# From Paul Eggert (2018-10-25):
# On 1921-03-04 federal law placed all of Texas into the central time zone.
# However, El Paso ignored the law for decades and continued to observe
# mountain time, on the grounds that that's what they had always done
# and they weren't about to let the federal government tell them what to do.
# Eventually the federal government gave in and changed the law on
# 1970-04-10 to match what El Paso was actually doing. Although
# that's slightly after our 1970 cutoff, there is no need to create a
# separate zone for El Paso since they were ignoring the law anyway. See:
