When you say, "have the TSE be accurate", do you mean "have the time (obtained from the event system and corresponding to the most recent arrival of the event whose number is in the record TSE field) be accurate"?  
The TSE field doesn't hold a time value -- it merely specifies the source from which a time value is to be obtained.

If the image frames are tagged at the moment they are acquired the TSE should be valid, even though by the time the records process it may not be the same pulse.  Wouldn't it be useful to have the TSE be accurate for such PVs even if they don't finish processing until 1 or more events later?
