@Lord Pendragon: There's no bookkeeping involved... any use within the last 8 hours should still be fresh in memory.

And really, it doesn't need to be "precise on the minute". It's just a rough guideline with a similar restriction spellcasters have with their recent casting limit.
There absolutely is bookkeeping involved. I have to start keeping track of the time of day that I use each ability. For instance, I currently play an 8th-level paladin. He can Smite twice a day. Last session, he Smote something.
Doing it your way, I'd have to note the time of day he did it, because his ability to Smite cannot be recharged until at least 8 hours have passed. Now let's say next session goes by without much conflict, until he's ambushed in the middle of the night, and he needs to Smite something again. I'll need to log
that Smite as well, so I can calculate, when morning comes and he performs his daily prayer, which of his Smites has had at least 8 hours to recharge, and which still won't be available.
Then, every combat that day, I'll have to start by asking my DM how many hours it's been since dawn, so I can see if I have one or the other use of Smite back again.
Ugh.
Every day at dawn, when my paladin prays to Pelor, his Smite attempts recharge along with his spell slots. Short and sweet. Yes, if he's ambushed at 3am and hasn't used them the following day, he can Smite twice, then four hours later (after he's prayed at dawn), Smite twice again. I see no problem with this. It rarely, rarely ever happens. And even when it does, there's no imbalance. And I, as a player, never need to worry about what time of day it is.
I understand that some people have more tolerence for bookkeeping than I do. But for myself, I can't imagine doing it any other way.
