Actually the asyn devEpics layer is simpler than described above.  
	- It always sets the record TIME field from the pasynUser->timestamp in the device support interrupt callback or read method then returns to higher level record processing code.
	- The record processing code then overwrites the TIME field unless the TSE field is -2.

I've sent a patch file with some proof-of-concept changes.   Hopefully Mark will have time to check them and commit the changes to the subversion repository some time next week.
