Time stamp question

[Andrew Wagner <apwagner@u.washington.edu>]

Hey guys, 

I have a Calcout record that needs to calculate the time between its present and previous processing. How can I best accomplish this? 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 

record(ai, "TIme") { 
  field(DESC, "System Time")
  field(DTYP, "Soft Timestamp")
  field(INP, "%s")
}

that gets seconds since the epoc I can use as an input to Calcout record? 

Cheers, 

Andrew
