Bumps tzdata from 2023.4 to 2025.2.

Release notes

Sourced from tzdata's releases.

2025.2: Release of upstream tzdata 2025b

Version 2025.2

Upstream version 2025b released 2025-03-22T20:40:46+00:00

Briefly:

New zone for Aysén Region in Chile which moves from -04/-03 to -03.

Changes to future timestamps

Chile's Aysén Region moves from -04/-03 to -03 year-round, joining Magallanes Region. The region will not change its clocks on 2025-04-05 at 24:00, diverging from America/Santiago and creating a new zone America/Coyhaique. (Thanks to Yonathan Dossow.) Model this as a change to standard offset effective 2025-03-20.

Changes to past timestamps

Iran switched from +04 to +0330 on 1978-11-10 at 24:00, not at year end. (Thanks to Roozbeh Pournader.)

2025.1: Release of upstream tzdata 2025a

Version 2025.1

Upstream version 2025a released 2025-01-15T18:47:24+00:00

Briefly:

Paraguay adopts permanent -03 starting spring 2024. Improve pre-1991 data for the Philippines. Etc/Unknown is now reserved.

Changes to future timestamps

Paraguay will stop changing its clocks after the spring-forward transition on 2024-10-06, so it is now permanently at -03. (Thanks to Heitor David Pinto and Even Scharning.) This affects timestamps starting 2025-03-22, as well as the obsolescent tm_isdst flags starting 2024-10-15.

Changes to past timestamps

Correct timestamps for the Philippines before 1900, and from 1937 through 1990. (Thanks to P Chan for the heads-up and citations.) This includes adjusting local mean time before 1899; fixing transitions in September 1899, January 1937, and June 1954; adding transitions in December 1941, November 1945, March and September 1977, and May and July 1990; and removing incorrect transitions in March and September 1978.

Changes to data

Add zone1970.tab lines for the Concordia and Eyre Bird Observatory research stations. (Thanks to Derick Rethans and Jule Dabars.)

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
