filemtime:
     Note: The results of this function are cached. See clearstatcache() 
for more details.

Seems that a cache for this in the database takes more resources than 
the PHP function...

It can however be a clever idea to have multiple caching levels. If we 
have a small cache in memory which can hold small amounts of data which 
are needed frequently this could really help reduce the number of 
database requests.
Before deciding to build such a thing statistics about cache hits and 
misses, size of items, number of requests for same item, etc. are really 
useful.
