I got paid double time for an hour that didn't exist.
We had to get a machine out to Hanover Fair, so we came in to the factory on Saturday morning to finish it. (I was coding the EPROMS that actually drove it). Sunday morning we'd finished all we could in that time, and it was packed and shipped.
To thank us, they paid us all double time for the hours worked, specifically including the hour skipped when the clocks went forward.
