I don't know. I've been away all day, and checking it again now I can't
get it to fail any more. Is anyone still having trouble updating their
trunk image?

Intermittent issues would not be entirely surprising in a case like this.
Anything involving Monticello is going to do a lot of DateAndTime stuff,
and there are various processes in your image that are also doing
Chronology things. If things get out of whack for a short period of
time during updating, it is certainly possible that intermittent errors
might happen.

These discussions are part of the reason that I think it will be a good
thing when we get Chronology moved into its own package. It is also the
reason that I am nervous about doing the package move, because it
introduces the possibility of totally screwing up the update stream.
