"Next Leve Allowance" is when you get your next set of guildleves, I think it's 3 every 12 hours?

"Next Map Allowance" (if you have it) is when you are able to find a treasure map through gathering.

In both cases you get both a time remaining shown (hours : minutes) and the actual date/time they will be replenished. Unlike the company timer those are both correct as far as I can tell.
