fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

8b45db8ee2 date(1): Make -r behave like GNU's version when the option can not be
interpreted as a number, which checks the file's modification time and
use that as the date/time value.

This improves compatibility with GNU coreutils's version of time(1).

b69ced8d8c date(1): Add "-R" flag to use RFC 2822 date and time output format
As stated in the man page, this is equivalent to use "%a, %d %b %Y %T %z"
as the output format while LC_TIME is set to the "C" locale.

This is compatible with date(1) from the GNU core utilities.

902d9eafbf Rework all non-contributed files that use `struct timezone'.
This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

	int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

9b796f4419 Let date(1) use utmpx instead of logwtmp().
utmpx also has OLD_TIME/NEW_TIME messages, which seem to be intended for
the same purpose as how we call logwtmp() here.

662713f2a8 Rev. 1.32 moved a comment to the wrong line. The hack refered to
in the comment applies to a decision that needs to be made in relation
to the year 2000.

In fact, that statement probably should be changed to be
more generic (getting the year from the current time perhaps). Otherwise,
starting in 2069 two digit year conversions in date(1) will start assuming
1900 instead of 2000. hehe.

something acceptable.

3bc1b1bb27 the month and three days are up for -hackers and the 24hrs for -committers.
add a -j flag that tells date not to try to set the date.  This allows you
to use date as a userland interface to strptime.

example:
TZ=GMT date -j -f "%a, %d %b %Y %T %Z" "Sun, 08 Nov 1998 02:22:20 GMT" +%s

which is the standard format for Last-modified headers in HTTP requests.
