# Following section was added for tz database 2018a and 2018b.
# ICU has a bug handling negative DST, and we also don't want to
# flip sumer time name and winter time name for Dublin at least for
# now. Because the change had major impacts to tz database external
# consumers, the tz database maintainer once reverted the Europe/Dublin
# rules (same as 2017c or older) in 2018c. The tz database maintainer
# thinks the changes in 2018a should be brought back when external
# tz database consumers are ready to adopt the change. We don't know
# what CLDR TC want to do with this for now. But if tz database brings
# back the change, and CLDR TC (and ICU TC) want to keep the display name
# unchanged, then we can uncomment the block below to restore ICU
# custom override. (Yoshito 2018-01-23)
#
# tzdata2018a changed Europe/Dublin to use IST (UTC+1) as the standard time
# of the region, and GMT (UTC) as the daylight saving time with negative
# offset (-1 hour) in winter. ICU SimpleTimeZone rejects a zone with negative
# daylight saving time offset. We could remove the restriction in newer version
# of ICU, but such data does not work well with older ICU runtime without
# fixing the issue. For now, we define our own Europe/Dubin in ICU, replacing
# Europe/Dublin data from the tz database.
#
#
# tzdata2018e suggests to use alternative zone definitions for use GB-Eire
# and EU rule after Oct 27, 1968. (Yoshito 2018-05-04)

# End of rearguard section.
# BEGIN Android-changed: Use rearguard policy for Casablanca and El Aaiun.
# From October 2018, these zones will be GMT+1 for 11 months of the year (in the
# Islamic calendar) and GMT+0 in the month of Ramadan. The ICU change that
# introduced this behaviour for 2018h/i implemented it as a raw GMT offset that
# changes twice a year, and no DST. This causes problems with code which relies
# on GMT offset changes being rare (such as java.time.format). It also causes
# problems because now java.util.TimeZone and android.icu.util.TimeZone differ.
# This change was made by taking the data from the rearguard.zi file produced
# while processing the CLDR patch, replacing the parts of this file added in the
# upstream change with the relevant parts of rearguard.zi, and appending --ICU
# prefixes to zone and rule names to be consistent with the above.
