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.
Cheers,

There is device support in EPICS base for a stringin record to display the timestamp of a record.

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
