This update for timezone fixes the following issue:
- From systemd v249: when enumerating time zones the timedatectl tool will now consult the 'tzdata.zi' file shipped by
the IANA time zone database package, in addition to 'zone1970.tab', as before. This makes sure time zone aliases are
now correctly supported. This update adds the 'tzdata.zi' file (bsc#1188127).

This update was imported from the SUSE:SLE-15:Update update project.
