When specifying the time in the form HHMM or HH:MM, if that time
is already past, the next day is assumed. Handle the case where
we're still in the same hour but the minutes are past.

Use warn/warnx here too.

Remove bogus DST code. mktime() handles DST automatically when
tm_isdst is set to -1.

Use __progname instead of the homegrown ProgramName.

Do not cast result of malloc/calloc/realloc* if stdlib.h is in scope

Eliminate use of TM_YEAR_BASE. OK guenther@ deraadt@ miod@

tzfile.h is an internal header that should never have been installed.
What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time. This makes the
tree safe for /usr/include/tzfile.h removal. The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree. Actual removal of tzfile.h is pending
a ports build. Based on a diff from deraadt@

Add the "next" keyword as an alias for "+ 1" for relative times.
Also support "months" and "years" keywords when specified as relative
time units. All as per POSIX. Man page changes OK jmc@ sobrado@

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

Sanity check the time argument specified by the -t argument. Some
checks adapted from date(1). Now prevents scheduling jobs in the
past just like the standard (ie: not -n) at(1) date parsing.

Cleanup, remove an unused var, use an int to store argc instead of a char,
makes lint a bit happier. OK deraadt

Remove trailing whitespace and, for printf, uid/gid are unsigned

Sync with ISC cron-current + my at(1) integration.
The at(1) code is now more tightly integrated into the cron codebase.

spelling; from Brian Poole <raj@cerias.purdue.edu>

Major changes:

Job names are now "runtime.queue" where runtime is when the job will run
in Unix time format. This is what SysV at does and allows us to nuke
the .SEQ file.

Historic BSD options for atq and atrm are now implemented;
atq and atrm get their own man pages.

At no longer does anything with the -v flag. We print the execution
time when jobs are submitted so there is no need.

Most *scanf() usage is gone (one remains in atrun).

Better sanity checks in atrun.

Random style/cleanup.

With these changes we have the best of both worlds; POSIX compliance with
the traditional BSD features.

Pass -Wall and use ANSI function headers.

Y2K fix. at(1) would die with 'garbled time' when assign_date() was passed
a year > 99. This change fixes the conversion of 2-digit years into
tm_year format.
