Description

This is a request for a GNUism. It is used by certain debian scripts like dch:

-R, --rfc-2822            output date and time in RFC 2822 format.
Example: Mon, 07 Aug 2006 12:34:56 -0600
--rfc-3339=TIMESPEC output date and time in RFC 3339 format.
TIMESPEC=`date', `seconds', or `ns' for
date and time to the indicated precision.
Date and time components are separated by
a single space: 2006-08-07 12:34:56-06:00

I'd be happy with just -R, although I can see that the other option may be quite useful as well.

Also, I notice that GNU date has %N, which is a time in nanoseconds. Perhaps this would be useful to obtain high resolution times?

For the log:
-R is basically the format "%a, %-e %h %Y %H:%M:%S %z". The only issue is to check whether any of these strings is subject to localisation.

As documented, date -R is rfc 822, and that is not subject to localization.

Furthermore, Linux date behaves with -R as:
"%a, %d %h %Y %H:%M:%S %z"

(Note that %d instead of %-e.) This is verified with

velocity{12}> date --version
date (GNU coreutils) 8.5

Taking this away from Roland due to lack of progress. I have a diff ready.
