Experimental Physics and
Industrial Control System

Marty:

Carl and I believe that you meant that the tse values that protect the
record's time stamp from being set by the time system should be:
epicsTimeEventDeviceTime (via device support) and
epicsTimeEventLinkPropagate(for flinks).

I take it now that there are three reserved values that this means that new
device support routines that could set the time stamp would have to check
for tse==epicsTimeEventDeviceTime  before setting the time stamp.
