> The failure is caused by this assert:
> assertTrue(s.created.before(now));
> It might be a coincidence, but it happened the same night as Europe was
> switching from DST.
> It may also be related to DERBY-5046, where a similar assert failed because
> poor clock resolution made the two timestamps equal.
