My Bosh ebike display can't set the clock unless I make an account with theminstall tje app, and agree to a huge, incomprehensible legal thing. It is a lousy time keeper, loosing 20 minutes over a year.

It will display a zillion fancy useless things to me, but my speed and the time are the only things I care about. I installed a speedometer next to it, which costs €10, looks ridiculous, and works.
