# Note:
#   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)
