Are you running a ntp daemon? UT3 uses gettimeofday(), thus it will 
crash if ntpd slows down the system clock while the server is running.

If you don't depend on real sync with timeservers, just shut down
services using gettimeofday(), use ntpdate to set the time
and restart services and the UT3 server again.

Note: ntpdate jumps once to sync time, ntpd tries to do this in forms
of slowing down or speeding up the system clock so that running services
don't crash. Just wait for the next patch if you _need_ ntpd.
