Bumps tzdata from 2025.3 to 2026.1.

Release notes

Sourced from tzdata's releases.

2026.1: Release of upstream tzdata 2026a

Version 2026.1

Upstream version 2026a released 2026-03-02T06:59:49+00:00

Briefly:

Moldova has used EU transition times since 2022. The "right" TZif files are no longer installed by default. -DTZ_RUNTIME_LEAPS=0 disables runtime support for leap seconds. TZif files are no longer limited to 50 bytes of abbreviations. zic is no longer limited to 50 leap seconds. Several integer overflow bugs have been fixed.

Changes to past and future timestamps

Since 2022 Moldova has observed EU transition times, that is, it has sprung forward at 03:00, not 02:00, and has fallen back at 04:00, not 03:00. (Thanks to Heitor David Pinto.)

Changes to data

Remove Europe/Chisinau from zonenow.tab, as it now agrees with Europe/Athens for future timestamps.

The changes made in this diff are updating the version of the 'tzdata' package. This is a routine update and there seem to be no issues with it. However, without context, it's difficult to assert if the update won't break anything. Developers should make sure to independently test the system to make sure this new version is fully compatible.
