07e8c324a8 tmdate(2): remove lies
Initially the code tried to guess the date format. This
turned out to be a bit too magical, so the feature was
removed, but the manpage still documented the nonfeature.

9f8d62ab64 libc: ignore '?' in date format strings
Ignoring '?' when formatting date strings allows
the format strings to be reused for parsing. This
is convenient, since we don't need to duplicate
the format strings.

732082c095 ctime(2), tmdate(2): document ctime/tmparse incompatibility
Tmparse and ctime don't mix. The timezone name may be
too long for the number of characters ctime mandates.
Document this footgun.

ce5b6036f0 tmdate(2): fix examples, stale references (thanks deuteron)
There were a number of ideas that were tried out as the tmdate
api evolved. As a result, there were some references in the
manpage to things that are no more.

Fix them.

4a1186ddfe tmdate(2): fix name of tm struct
There was a leftover from when this library was separate
with different types.

f444d6c3f2 tmparse: put in local timezone hack
Ctime is defined as printing a 3-character timezone
name. The timezone name is ambiguous. For example,
EST refers to both Australian and American eastern
time. On top of that, we don't want to make the
tzabbrev table exhaustive. So, we put in this hack:

Before we consult the well known table of timezones,
we check if the local time matches the timezone name.

On top of that, tm2sec

If you want unambiguous timezone parsing, use numeric
timezone offsets (Z, ZZ formats).

17abfa51ca libc: tmparse should ignore leading whitespace
We almost always want to skip leading whitespace in time
formats, so make tmparse just do it. This fixes upas mbox
parsing, which leaves a leading whitespace at the start of
the date.

56e869ac70 libc: new date apis
The current date and time APIs on Plan 9 are not good. They're
inflexible, non-threadsafe, and don't expose timezone information.

This commit adds new time APIs that allow parsing arbitrary
dates, work from multiple threads, and can handle timezones
effectively.

febe84af75 libc: revert date change again. this is getting ridicuoulus.
this breaks the sample from the seconds manpage, and overall
produces funky results. this needs alot more testing.

term% seconds '23 may 2011'
seconds: tmparse: invalid date 23 may 2011 near 'may 2011'

term% seconds '2019-01-01 00:00:00'

8b3efcfc4e libc, seconds: new time and date apis (try 2)
Redo date handling in libc almost entirely. This allows
handling dates and times from outside your timezones,
fixes timezone loading in multithreaded applications,
and allows parsing and formatting using custom format
strings.

As a test of the APIs, we replace the formatting code in
seconds(1), shrinking it massively.

The last commit missed a few removals, and made it
unnecessarily hard to do an update.
