Do you mean using fine-grained timestamps when timestamps of a file has been
recently queried/modified BUT its coarse-grained timestamps aren't changed?

Confused...
Yes, I'll do an s/and/but/ there in the Documentation. Basically, we
want to avoid updating the floor whenever we can (since it's a global
variable), so we only get a fine-grained time if there is no other way
to effect a change to the timestamps.

Thanks!
