The branch releng/15.0 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=0948c4d4a3308737879342d87efc311913ee4335 commit 0948c4d4a3308737879342d87efc311913ee4335 Author: Gordon Tetlow <gordon@FreeBSD.org> AuthorDate: 2025-10-15 22:24:06 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2025-10-22 20:12:30 +0000 libc: Add "Z" as TZ designator for strptime. ISO 8601 allows use of "Z" as the time zone designator. Update the strptime parser to allow this usage. While we are at it, update the manpage to reflect that both UTC and Z are now valid options.
