It certainly is useful and I gave an obvious and real-
world example in my previous post.

Why?  When I turn the adjustment knob on my analog
clock it crosses the day boundary from 23:59 to 0:00
with no problem whatsoever.  Why is Python unable
to do what billions of clocks do? 

Instead I have to convert everything to seconds and
do the same math I would have done in fortran in 1980.
Phew.

Another example of Pythonic "purity beats practicality"
