The core functionality would look like this:

record(stringin,"clock") {
  field(DTYP,"Soft Timestamp")
  field(INP,"@%H%M%S")
  field(SCAN,"5 second")
  field(FLNK,"check")
}
record(calcout,"check") {
  field(INPA,"clock")
  field(CALC,"A>235950?1:0")
  field(OOPT,"Transition To Zero")
  field(OUT,"do_reset PP")
}
record(seq,"do_reset") {
# do all the steps to reset the integral here
}

All background information is in the Record Reference Manual:

Good luck!

Yet another idea:
The stringin record has support for strftime formats. If you use that to create a six digit hhmmss number, you can use a calcout record to e.g. check for <10 and process a seq record on the 1->0 edge to do the integral reset sequence.
That’s a brilliant way to get the local time, without calling out to C code (subroutine rec, SNL), as a number!

Yes, do that. Disregard everything else I wrote.

Guys thanks a lot for your suggestions

But would you mind to be more specific on how can i do it? I am quite new to EPICS and i am not really into this subjects yet.
