The jobs need to run at midnight, local time. Which shifts from UTC. How to handle?

Why does it need to run at that time?

* If it's being run to scrap data from a source that's available at some time, adjust the job if the source changes its time.

* If it's being run "when its dark and no one is around" then it'll run at some part of the dark bit regardless of DST changes.

		Sometimes you minimize downtime by running something while some other system you don’t control is down.

Use UTC, and stop faffing about with changing localtime twice every year so the offset is a constant?
