> screwing up Is it wrong just because the clock time is wrong? Or is the data actually going to get corrupted? In my experience, reports are usually reporting on a period of time, and it doesn't actually matter if the job runs an hour off since you don't want them to be time sensitive in the first place (e.g. you might get noise because some query became very expensive for some reason and delayed a portion of the job by an hour, or the job ran in a data center in a different state, etc). Besides, this isn't really the same class of problems that the "use UTC" advice targets. Crons are a far better tool for daily scheduled jobs. The UTC advice is for systems that communicate dates across multiple machines.
