It's my impression there are two camps with an interest in date/time.

The first group needs it for 'business' applications to do global
calendering operations.
A second group wants it for timing routines/algorithms.

Where the first group needs a class that represents global time,
the second group needs all the accuracy they can get. 
A lightweight class using only one datamember
(e.g. clock_t) can not satisfy both groups (datarange is
too limited). Increasing the size of the class on the other
could increase the overhead (which is of utmost importance
to the second group).
Maybe there is an approach which works for both but I just
wanted to raise the point and look at the scope of the
problem before thinking about a solution.
