Well, clock drift and/or timestamp resolution (as long as it's within
a second or so) wouldn't matter -- we're not comparing time across two
machines, nor are we even comparing a file's timestamp with the system
clock. Instead, we'd be comparing the timestamps of two files, whose
timestamps had earlier been explicitly set to be the same.

But recording a discovered timestamp and comparing those two is
probably going to be more reliable than trying to set timestamps
portably.
