Control: affects -1 + src:tzdata
[ Reason ]
Include the changes found tzdata 2023c into the bullseye package, namely
the change to Lebanon DST. Given the confusion about DST in Lebanon, and
with a point release so close, I haven't judged necessary to go through
stable-updates.
[ Impact ]
Users in Lebanon will still have the wrong time.
[ Tests ]
There are not tests for the current change.
[ Risks ]
The change is trivial and is based on upstream change, and is in sid for
almost 3 weeks.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
This basically reverts the change done in version 2021a-1+deb11u9 to
match the status quo about DST in Lebanon. It's best summarized by the
upstream changelog: "Model Lebanon's DST chaos by reverting data to tzdb
2023a".
[ Other info ]
I have already uploaded the package to the archive. Thanks for
considering.

++# Lebanon ... announced today delay of Spring forward from March 25 to April 20.
++#
++# From Paul Eggert (2023-03-27):
++# This announcement was by the Lebanese caretaker prime minister Najib Mikati.
+ # https://www.mtv.com.lb/en/News/Local/1352516/lebanon-postpones-daylight-saving-time-adoption
++# A video was later leaked to the media of parliament speaker Nabih Berri
++# asking Mikati to postpone DST to aid observance of Ramadan, Mikati objecting
++# that this would cause problems such as scheduling airline flights, to which
++# Berri interjected, "What flights?"
++#
++# The change was controversial and led to a partly-sectarian divide.
++# Many Lebanese institutions, including the education ministry, the Maronite
++# church, and two news channels LCBI and MTV, ignored the announcement and
++# went ahead with the long-scheduled spring-forward on March 25/26, some
++# arguing that the prime minister had not followed the law because the change
++# had not been approved by the cabinet. Google went with the announcement;
++# Apple ignored it. At least one bank followed the announcement for its doors,
++# but ignored the announcement in internal computer systems.
++# Beirut international airport listed two times for each departure.
++# Dan Azzi wrote "My view is that this whole thing is a Dumb and Dumber movie."
++# Eventually the prime minister backed down, said the cabinet had decided to
++# stick with its 1998 decision, and that DST would begin midnight March 29/30.
++# https://www.nna-leb.gov.lb/en/miscellaneous/604093/lebanon-has-two-times-of-day-amid-daylight-savings
++# https://www.cnbc.com/2023/03/27/lebanon-in-two-different-time-zones-as-government-disagrees-on-daylight-savings.html
++#
++# Although we could model the chaos with two Zones, that would likely cause
++# more trouble than it would cure. Since so many manual clocks and
++# computer-based timestamps ignored the announcement, stick with official
++# cabinet resolutions in the data while recording the prime minister's
++# announcement as a comment. This is how we treated a similar situation in
++# Rio de Janeiro in spring 1993.
