That makes very little sense for filesystem encryption.
And actually, I do not believe there is any good way
way of implementing such a concept in the first place.
Time is just a number to a cryptosystem, and that
number is one of the very few things that can be well
predicted, hence it can be faked.
Thinks like hardware modules that release a key after a
predefined time do not count. They are not a cryptographic
approach.
