In looking for a refinement of the lxpanel digital clock
format to get '01:35pm' to read '1:35pm', I found some-
thing more immediately interesting:

I found someone other than myself whose digital clock is
(or was) one minute (or so) off. My GE stove is keeping
better time.

It's not clear (to me) if the 'archlinix bug fix' is
available through Synaptic as yet. I am presuming it is
contained in lxpanel itself and not some another element.
