Update tzdata to version '2026a'

actions-user · actions-user · commit 53f247e8b897 · 2026-03-02T21:51:51.000Z
# 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.
