clock scan [clock format [clock seconds] -gmt 1]

fails with:

unable to convert date-time string "Tue Dec 20 17:41:41
+0000 2005"
while evaluating {clock scan [clock format [clock
seconds] -gmt 1]}

The default format has changed from 8.4 to current CVS.

tclsh8.4 [~]clock format [clock seconds]        
Tue Dec 20 01:00:34 PM EST 2005

tclsh8.5 [~]clock format [clock seconds]
Tue Dec 20 13:02:10 -0500 2005

Not sure if this was desired, but a trivial patch
(attached) restores the old behaviour.

In the 8.5 HEAD, I've put [clock format] back to using
the timezone name rather than the value.  We really, really
need to make positive as well as negative timezones work
in free-form [clock scan] - but that's a tremendous
amount of work.  There are simply too many ambiguities for
the YACC parser to do The Right Thing.  I'm leaving this
open because I have some other ideas (short of resorting
to fixed-format [clock scan]) for fixing this in 8.5.

But maybe [clock scan] should be able to handle more formats ?
