Sure -- you can do that -- as long as you don't actually want to do 
anything with the time other than print it.  ;-)

As you said, you don't have any purpose in mind for date / time support, 
but most of the time people working with dates / times do in fact have 
something in mind that they want to do.  Here are a couple examples of 
date / time APIs:

But let's say that you want your ChucKoo clock to let you sleep in on 
Saturday.  Well, then you need your date / time class to be able to 
report the day of the week.  Or if you want to say, "How much time is 
there between now and tomorrow at noon?"  You need to have API support 
for adding and subtracting time.
