Difference in Time Zone data

  • 772

I've entered into Ubuntu recently and got an issue with timezones.

I've got 1794 count in Centos Server of 7 version.

tzdata version Command: rpm -q tzdata Output : tzdata-2024a-1.el7.noarch

But I've got 454 count in Ubuntu Server of 24.04 version.

Command: dpkg-query -W tzdata Output: tzdata 2024a-3ubuntu1.1

Because of this difference i'm facing timezone issue for my applications.

Please check and provide me some resolution.

24.04

    The Asia/Calcutta timezone designation appear to have been moved into the tzdata-legacy package:

    $ apt-file list tzdata-legacy | grep Calcutta
tzdata-legacy: /usr/share/zoneinfo/Asia/Calcutta
tzdata-legacy: /usr/share/zoneinfo/right/Asia/Calcutta

    with the primary tzdata package now providing only Asia/Kolkata to reflect the city's current official English spelling1:

    $ apt-file list tzdata | grep Kol
tzdata: /usr/share/zoneinfo/Asia/Kolkata

    From /usr/share/doc/tzdata/NEWS.Debian.gz

    tzdata (2023d-1) unstable; urgency=medium

    From 2023c-8 on the tzdata package ships only timezones that follow the
    current rules of geographical region (continent or ocean) and city name.
    All legacy timezone symlinks (old or merged timezones mentioned in the
    upstream backward file) were moved to tzdata-legacy. This includes the
    US/* timezones.

    Please install tzdata-legacy in case you need the legacy timezones or to
    restore the previous behavior. This might be needed in case the system
    provides timezone-aware data over the network (e. g. SQL databases).

    Installing the tzdata-legacy package should make the older Asia/Calcutta available on your system.
