Hi Andrew,
I use the following an database to tell me when 1 minute has elapsed ... not
sure that this will help with what you need but it might give you another idea.
record(stringin,"S:SRsecsPastEpochSI") {
        field(DESC,"Seconds Past Epoch")
        field(DTYP,"Soft Timestamp")
        field(SCAN,"1 second")
        field(FLNK,"S:SRsecsPastEpoch PP NMS")
        field(PINI,"YES")
        field(INP,"@%s")
}
record(scalcout,"S:SRsecsPastEpoch") {
        field(DESC,"Sec Past Epoch")
        field(DTYP,"Soft Channel")
        field(CALC,"INT(A)-INT(B)")
        field(INPA,"S:SRsecsPastEpochSI.VAL NPP NMS")
        field(INPB,"631152000")
        field(OOPT,"Never")
        field(FLNK,"XFD:IntervalMinute PP NMS")
        field(PREC,"0")
        field(EGU,"Sec")
}
record(calcout,"XFD:IntervalMinute") {
        field(CALC,"A%B = 0? 1:0")
        field(INPA,"S:SRsecsPastEpoch.VAL NPP NMS")
        field(INPB,"60")
        field(OUT,"XFD:FillArrays.PROC PP NMS")
        field(OOPT,"Transition To Non-zero")
}

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
