What about issuing a warning event when timestamps from low level differs significantly from local clock? This might prevent some time-synchronization problems.. Shall I start a JIRA ticket for this or you will be able to add this check now? I am not sure if there is any warning event in ts_rotator XML available for that..

Or maybe even better, rejecting low-level updates when timestamps differ..

I worry it will require too much code for little gain. It requires configuring a max tolerance, then dealing with the fact that the data arrives at 10-20 Hz and I certainly don't want to print warnings at that rate, so I need logic for "I have already reported this", and a way of resetting that after N "in spec" times. If you feel strongly about it feel free to file a ticket. A Watcher alarm is another option (though I'd rather not have it responding to an event at that rate if I can avoid it, which suggests polling...)
