| People are very used to the idea of a date and a time
| of day going together and specifying a point in time.
| Having separate Date and TimeOfDay classes may be a
| good idea, but many people are going to be disappointed
| if there isn't also a DateTime class that blends
| them smoothly together somehow.
No, no, no. I never meant to advocate a TimeOfDay class without
reference to the date. If you need to specify a time, you need the
date to go with it, or the time is useless. So there should be a Date
or Calendar class that merely understands dates and calendars, with no
reference to time of day. And there should be a Time class, which
specifies a time by giving both the date (from the former class) and a
time of day. (Complete with time zone information.) All I'm saying
is that the first module needs to be nailed down dead solid before
you even start tackling the second.

- Yes it works in practice - but does it work in theory?
