Morocco moves to permanent +00 on 2026-09-20. More integer overflow bugs have been fixed in zic. Changes to future timestamps Alberta’s 2026-03-08 spring forward was its last foreseeable clock change, as it moved to permanent -06 thereafter. (Thanks to Roozbeh Pournader and others.) Model this with its traditional abbreviation CST. Although the change to permanent -06 legally took place on 2026-06-18, temporarily model the change to occur on 2026-11-01 at 02:00 instead, for the same reason we introduced a similarly temporary hack for British Columbia in 2026b. Although another TZDB release will likely be needed soon because Northwest Territories will likely follow Alberta, the legal formalities have not yet taken place. Morocco plans to move back to permanent UTC, without daylight saving time transitions, on 2026-09-20 at 02:00. This also affects Western Sahara. Changes to code zic no longer overflows integers when processing outlandish input like ‘Zone Ouch 0 - LMT 9223372036854775807’, ‘Zone Ouch 0 2562047788015215 LMT’, ‘Zone Ouch -2562047788015215:30:08 - LMT’, and ‘Zone Ouch -2562047788015215:30:08 - %%z’. This avoids undefined behavior in C. (Problems reported by Naveed Khan.) On platforms that have EFTYPE, tzalloc now fails with errno set to EFTYPE, not EINVAL, if it detects that the TZif file has an invalid format or is not a regular file. Formerly it did this only on NetBSD, and only when the file was not a regular file. Unprivileged programs no longer require TZif files to be regular files or reject relative names containing ".." components. This reverts to the more-permissive 2025b behavior, as the stricter behavior did not catch on in FreeBSD. zic now reports any failure to remove a temporary file when cleaning up after a previous failure. (Problem reported by Tom Lane.) Changes to commentary Northwest Territories is expected to move to permanent -06 prior to 2026-11-01 02:00, when clocks would otherwise fall back. (Thanks to Tim Parenti and James Bellaire.) Model this with its traditional abbreviation CST. Unfortunately the change is not yet official, so it is currently present only as comments that can be uncommented as needed. Changes to build procedure The undocumented ‘typecheck’ Makefile check rule has been removed. It stopped working in 2025a and evidently nobody noticed. The rule was superseded by ‘check_time_t_alternatives’ in 2013d.
