2025-10-15libc: Add "Z" as TZ designator for strptime.Gordon Tetlow
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. Reviewed by: des MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D53083

2024-12-09strptime: Fix day-of-week calculation.Dag-Erling Smørgrav
The day-of-week calculation used the raw year value without adjusting for TM_YEAR_BASE, so it was off by one for 300 years out of every 400; it just happened to be correct for 1901 through 2000. It also used a loop where a simple addition would have sufficed. While here, simplify our version of Gauss's algorithm, and document that we assume the Gregorian calendar.

2024-03-11timezone: Move to the XSI/POSIX definition for timezone.Warner Losh
The old timezone(3) function has long since been obsolete and has a fatally flawed interface. Retain this function for compatibility purposes, but shift to providing the offset from UTC in the timezone variable, whether or not the timezone observes summer time in the 'daylight' variable. Document the tzname variable that's already been set. Also make _tztab() static. It's not used in libc (or anywhere in the tree) and it's not exported as a public dynamic symbol.

2017-11-25libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326193

2017-01-20Replace dot-dot relative pathing with SRCTOP-relative paths where possibleEnji Cooper
This reduces build output, need for recalculating paths, and makes it clearer which paths are relative to what areas in the source tree. The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS. LIBC_SRCTOP was left alone so Juniper (and other users) can continue to manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as include Makefiles with custom options.

Add support for the missing POSIX-2001 %U and %W features: the existing FreeBSD strptime code recognizes both directives and validates that the week number lies in the permitted range, but then simply discards the value. Initial support for the feature was written by Paul Green. David Carlier added the initial handling of tm_wday/tm_yday. Major credit goes to Andrey Chernov for detecting much of the brokenness, and rewriting/cleaning most of the code, making it much more robust.
