What scripts (e.g. the serial-voting script) run at 3:00 UTC, as opposed to once every minute, few minutes, or
6 to 8 weeks?
This question was inspired by a specific thing I encountered: seven posts that I edited were removed at exactly 3:00 UTC, lowering my reputation by 14. While I did ask this question to figure out why that happened, it is not about that problem and only that problem, so please answer accordingly.
