[Nut-upsuser] Is a timer a file?

[Roger Price]

Hi, I'm trying to get a better understanding of what a timer is, so I 
added the following line to upssched.conf

  # Debug - turn on long-running timer to find out where upssched puts it
  AT ONBATT * START-TIMER where-am-I 1000

I can then start this timer by pulling the power cord from the wall for 
just a few seconds.

I now have 1000 seconds to find the timer.  I don't see it in /var/lib/ups 
where the locate tool finds upsd.pid, and I don't see it in /run or 
/var/run where I see upsmon.pid.

Is a timer a file?, and if it is, where should I find it?  Any suggestion 
would be much appreciated.  Thanks, Roger
