I have more info on this now, but still don't know where best to report it.
The additional info is that logging out and logging back in -- which is
something I rarely do; I often go weeks without doing so, but I happened to do
it today -- "fixed" the problem.
So what appears to happen (this is a guess, but it fits the evidence) is that
the clock figures out the time in London at log-in time, and then starts
free-running, keeping the same offset between the displayed time and UTC,
regardless of subsequent changes to/from summer time that might occur during
the logged-in session.
In any case, the fact that the clock is unreliable and can display an
incorrect time is obviously a bug, and I would hope that someone can look into
the issue. (FWIW, the local clock -- Denver -- quite happily adjusted the time
automatically and correctly earlier in the month.)
