how many blocks are how old?

[roger long]

Does anyone have any sort of utility that can be used on a filesystem
to give you a run-down on file/block aging?  I'd like to be able to
run it on, say, /usr/spool, to let me know how many blocks are one day
old, two days old, 30 days old, etc.

Something that gave other statistics of interest might be useful as well.
