No, my wife watches 'Gilmore Girls' and there is a business on that
show called the Dragonfly Inn' so she chose dragonfly. I like the name
though.

No, I should have said that I set TIMEZONE="America/Los_Angeles" even
though I'm north in the SF Bay Area.

I did, and I have rebooted. I *think* things are right but I'm trying
to be careful. There seem to have MythTV problems all over the place
yesterday with Zap2It labs possibly having shows at the wrong times,
etc., so it's unclear where all the problems might be.

OK, I need to go read somewhere. Actually, that part you wrote is very
clear, but isn't UTC time the same as Greenwich Mean Time? Maybe GMT
isn't effected by DST?

I normally think of California being 8 hours behind GMT. 3AM seems to
be 7 hours behind UTC and not 8 hours. Since we got DST 3 weeks early
maybe GMT didn't shift yet? Or maybe GMT never shifts?

Leave it to the American government to create world wide problems.
(Not the first time, obviously and unfortunately not the last.)

Thanks,
Mark
