Is there any reason that it's configured this way?
I expect it's because 23:00 to 07:00 are usually quiet hours when people are most likely to be sleeping and some cron jobs do work the CPU enough for cooling fans to speed up, or access hard disks enough that they become noisy. Intermittently-on computers are often located where people live.
Extra noise during cron jobs may not be universal now with fanless/quiet computers and SSDs and so on, but it is probably still common enough for it to be a sensible default.
I know when I had a rack server in a home office temporarily a few years ago, I could tell that cron.daily typically ran at 1am!
Hope that informs,
