Real reason is probably that the schools don’t have the budget to pay for the batteries, or for someone to make sure the time is correct on all of them in the school…
My high school all the analog clocks attached to a big box that had the intercom in it. The clocks were all synchronized remotely through that system school wide. So no need for batteries. We did have digital clocks at the ends of most hallways. I’d imagine because they’re just physically smaller and less ambiguity for when 1 minute matters before a bell in between classes.
