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.

strptime: Fix day-of-week calculation.2024-12-09T12:38:22ZDag-Erling Smørgravdes@FreeBSD.org2024-12-09T12:37:45Zurn:sha1:4285e024baa80f81d13cdcc016fdf0721fe57862
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.

* Mention that mktime() and timegm() set errno on failure.
* Correctly determining whether mktime() / timegm() succeeded with
arbitrary input (where -1 can be a valid result) is non-trivial.
Document the recommended procedure.

timezone: Move to the XSI/POSIX definition for timezone.2024-03-12T04:19:31ZWarner Loshimp@FreeBSD.org2024-03-12T04:19:05Zurn:sha1:a34940a9756ac8edce36fec176949ee82e9235b4
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.
