That's the bit I'm skeptical about. It's worth looking into as it
would be a *very* serious bug but I am highly skeptical that it is
happening as you describe. A bug in the statcache code alone could not
do that, we'd need to have a bug in become_user() or the vuid map.

Little things to check for are that utmp entries are taking into
account DST in the same way the client is. That 1 hour could make all
the difference.
