That's not strictly true though, is it?  E.g. clock_gettime() returns the
number of seconds since the Epoch, which is a well-defined start time at least
on *nix systems.  So clearly those types of functions could return datetimes.

I'm fairly certain that between those types of functions and timedeltas you
could have most of the bases covered.
