This is a longshot, but it's daylight savings time of year. We just
moved from +10 to +11 hours at around 2am on Oct 3. I'm sure it's just a
coincidence as I can't see how changing a timezone offset could cause
such a problem but I've seen a few strange things this week with clocks
getting out of whack.
