I have checked our machines and they aren't running ntpd, but they were synchronised with ntpdate. The date command showed the wallclock was in sync and clock -r showed the rtc was also in sync. Both cases have a delay of at most 1 second.
I ran my tests again to ensure they are still in sync, which they are.
