Donzt beat me for this, but grub2 sounds more like a kernel every day.

I almost want to suggest nicking things from hurd.

Grub2 could even be the init on a minimal hurd setup, surely?

Yes, I am reluctant to use loops for that reason.

I could definitely do a simple read RTC in a loop until the time
difference from when I started the loop is what I want it to be...

I'll try to get that working, but I am open to other suggestions as well!
