Time Based Entity Cache

Hi,
At the moment if I understand correctly, Entity Cache has a permanent cache that's cleared if the entity changes.
In my situation, because we have very agressive caches for anonymous users (1 day), we would like to avoid having logged in users seeing content before anonymous users.
We would like to force caches to persist for a period of time, until we clear caches (making our changes visible) and re-warming our caches for the next day.
Is there any way to have a time based entity cache?
Thanks,
Duarte
