Hi Colin,

Werner's said he's in favour of this approach.  I'd just wonder if the
option of providing a timestamp in the environment variable would also
be useful.  Then user's are free to take it from Mercurial, etc.  The
format(s) should align well with other commands, e.g.

    $ stat -c %Y foo   # Modification time, seconds since the epoch.
    1367224459
    $

date(1) knows a -d date is seconds from the epoch by the leading `@'.
Perhaps the convention can be continued.

    $ date -ud @1367224459
    2013-04-29 08:34:19 +0000 Mon
    $

Cheers, Ralph.
