Re: [Condor-users] Is ActivationTimer daylight saving shift safe?

We use the $(ActivationTimer) macro in our MaxJobRetirementTime

And at 1:00 am on Sunday morning we saw some longer running jobs
suddenly get evicted. So the hypothesis is that the ActivationTimer for
these jobs went from a positive integer value to a negative value (or 0
value) as the daylight saving shift was applied to the clocks on our
startd's and thus set MaxJobRetirementTime back to 0 on these jobs so
they were candidates for eviction.

Is the macro daylight savings safe (is it a timer)? Or is it calculated
using (CurrentTime - JobStart)?

ActivationTimer is only defined in the config file. The condor daemons see (CurrentTime - JobStart). Condor uses epoch times for these values, so Daylight Saving Time shouldn't affect them, unless your system clock changes instead of just the time zone.
