tzdata 2023d release (leap-second.list expiring this week)

[Bill Thorsteinson]

[ Impact ]

leap-seconds.list shipped by tzdata 2023c expired on Dec 28th 2023.

The 2023d release contains the following changes:

   Briefly:
     Ittoqqortoormiit, Greenland changes time zones on 2024-03-31.
     Vostok, Antarctica changed time zones on 2023-12-18.
     Casey, Antarctica changed time zones five times since 2020.
     Code and data fixes for Palestine timestamps starting in 2072.
     A new data file zonenow.tab for timestamps starting now.

   Changes to future timestamps

     Ittoqqortoormiit, Greenland (America/Scoresbysund) joins most of
     the rest of Greenland's timekeeping practice on 2024-03-31, by
     changing its time zone from -01/+00 to -02/-01 at the same moment
     as the spring-forward transition. Its clocks will therefore not
     spring forward as previously scheduled. The time zone change
     reverts to its common practice before 1981.

     Fix predictions for DST transitions in Palestine in 2072-2075,
     correcting a typo introduced in 2023a.

   Changes to past and future timestamps

     Vostok, Antarctica changed to +05 on 2023-12-18. It had been at
     +07 (not +06) for years. (Thanks to Zakhary V. Akulov.)

     Change data for Casey, Antarctica to agree with timeanddate.com,
     by adding five time zone changes since 2020. Casey is now at +08
     instead of +11.

   Changes to past tm_isdst flags

     Much of Greenland, represented by America/Nuuk, changed its
     standard time from -03 to -02 on 2023-03-25, not on 2023-10-28.
     This does not affect UTC offsets, only the tm_isdst flag.
     (Thanks to Thomas M. Steenholdt.)

   New data file

     A new data file zonenow.tab helps configure applications that use
     timestamps dated from now on. This simplifies configuration,
     since users choose from a smaller Zone set. The file's format is
     experimental and subject to change.

[ Test Plan ]

Test cases were added to autopkgtest to cover the testing:

* python: test_2023d

So the test plan is to check that all autopkgtest succeeds.

[ Other Info ]

The autopkgtest for chrony is flaky on jammy and newer (see bug #2002910).

I have also been watching the days tick down to expiration.

I see that this has been fixed in Debian with tzdata 2023c-5+deb12u1. It would be great if an updated package would flow through Ubuntu.

I prepared the ESM updates for trusty, xenial, and bionic in git: https://code.launchpad.net/~ubuntu-core-dev/ubuntu/+source/tzdata/+git/tzdata

I installed tzdata_2023d-0ubuntu0.23.10_all.deb on a 22.04.3 LTS system with these messages logged.

    ntpd[2389941]: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): good hash signature
    ntpd[2389941]: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): loaded, expire=2024-06-28T00:00:00Z last=2017-01-01T00:00:00Z ofs=37

Looks good to me! Thanks!

Thank you!

[Bill Thorsteinson (billthor55)]

I have installed the proposed release and the file /usr/share/zoneinfo/leap-seconds.list expiry date is '28 June 2024'. A future update should be schedule for May. Thanks for the update.

Test regressions may be related to this change in 2023a data set. If so test should be updated accordingly.

Changes to past timestamps

     America/Yellowknife has changed from a Zone to a backward
     compatibility Link, as it no longer differs from America/Edmonton
     since 1970. (Thanks to Almaz Mingaleev.) This affects some
     pre-1948 timestamps. The old data are now in 'backzone'.

[Benjamin Drung (bdrung)]

All lunar autopkgtest succeeded. python-tz had to use 2022.7.1-3ubuntu0.1 from lunar-proposed.
