Going through Rational is the right solution, though. My hackish

Yes, that would be good! Note that both the docs for DiffTime and
EpochTime state that
they contain seconds, and both are somewhat unclear as to whether
they contain any
higher precision than whole seconds.
(a) Whether EpochTime contains higher precision than seconds is
system-dependent.
(b) Use of a non-Integral type for EpochTime does not necessarily
mean it has higher resolution than seconds.
(Blame POSIX for both of these. Haskell's System.POSIX must deal, as
must any other POSIX-compliant library.)
