Re: Time stamp question

  Andrew,
I'm using Ned Arnold's devTimeOfDay.c device support, which gets the current 
time into an ai or
a stringin record, for this purpose:

record(ai, "$(P)history$(N)_secsPastEpoch") {
  field(DTYP, "Sec Past Epoch")
}

There's a copy in the synApps std module.

Searching the tech-talk forum I've found that there is DTYP, "Soft Timestamp" which I suppose gets the system time. I would like to compute the time difference in seconds so is it possible to create an AI record
