pound of flesh to see what date -R will print

[Dan Jacobson]

$ date --help or man date:
       -R, --rfc-2822
              output date and time in RFC 2822 format
We must go look up the RFC and read it to find out what this
format looks like.

Or we must dig thru the long winded Info page.

Or we must try it
$ date -R
Sun, 25 Jun 2006 02:35:21 +0800

OK, that didn't hurt, but shouldn't need to try it to see what the
output will be. We might have been reading the page with no Unix
machine nearby.

Same problem with --rfc-3339=TIMESPEC etc.

I bet the http://www.useit.com/alertbox author would have put example
output for each item on the man page.
