I have tried the same code on different machines with identical clock.tcl
- one exhibits the problem, the other doesn't.

Could it have something to do with timezone?  The only difference I can
think of between the two machines is that they're in different timezones.

Identical input, as far as I can tell, against the HEAD:

% set f "%a, %d %b %Y %H:%M:%S GMT"
%a, %d %b %Y %H:%M:%S GMT
% clock format [clock seconds] -format $f -gmt 1

Is your Tcl self-built, or did you get it from a known distribution?
The reason that I ask is that I suspect a corrupted 'clock.tcl' -
specifically the code in the procedure ::tcl::clock::LocalizeFormat
that looks like:

    set format [string map [list %r [mc TIME_FORMAT_12] \
				%R [mc TIME_FORMAT_24] \
				%T [mc TIME_FORMAT_24_SECS]] $format]

That's the only place that %T is handled. And it's pretty clear that
it replaces %T with %H:%M:%S, not the other way around.

Can you check that your $::tcl_library/clock.tcl matches the HEAD?
I haven't done anything to clock.tcl since April, and as I said,
it Works For Me.
