You will need to run a soft IOC to generate timestamp PVs.
Here is a sample db record that will perform the desired task.

record(stringin, "${PV}:T") {
  field(DTYP, "Soft Timestamp")
  field(TSEL, "${PV}.TIME CP")
  field(INP, "@%b %d %Y %H:%M:%S")
}

Where ${PV} is the record you wish to monitor for update time.

There is device support in EPICS base for a stringin record to display the timestamp of a record.  Look at this tech-talk note:

Subject: Access TIME field of a PV

Hello,

I have a MEDM display with several text message PVs. The users want to know when the PVs last updated because they don’t update frequently, I thought it would be easy - I’d just display the TIME field next to the message, only to find that TIME is not accessible. So is there an easy way to display the last update time? I was hoping not to need to write code to do it.

Thanks for any suggestions.

Elmer Pensack
