Even with the sample code from LuaCombinator 2:

var["time"] = (var["time"] or 0 ) + 1
output["signal-A"] =var["time"]
delay=60

Edit: It does update on "ok" but never again.

lua combinator 2 runs every tick, with this one you need to assign functions to event variables like in the screenshot of this mod

OK thats not immediately obvious since "delay" is actually at the very top of this mod as well...

note delay can be set in every event, but only affects the on_tick event

How does delay actually work?

Taking the code of Ozbekov and changing it to count up once a second but delay doesnt actually.

var["time"] =0
on_nth_tick[60] = function (event)
   var["time"] = (var["time"] or 0 ) + 1
   output["signal-A"] =var["time"]
   delay=600
end
