Hmmm well I have found my problem but have not got a solution. NTP is changing the time on the system, and then
[1313911134.718762] [001.0] [pid=14714] compensate_for_system_time_change() start [1313911134.718767] [008.0] [pid=14714] Detected a backwards time change of 0d 0h 0m 1s.

There seems to be something unrequired here, the checks have been scheduled for a time time x, the real time, time y, has been adjusted but we still want the check to run at time x! Or to catch up as much as required running checks scheduled in the new past! Anyway, apart from not having the Virtual time move around on me, has anyone got any suggestions to stop the time rescheduling going outside the timeperiods?
