Ugh, that's irritating. I can't think of any scenario where I would
ever want the semantics "if timeval (is not midnight):".
Yes, it is a genuine gotcha. Time values are numbers, and zero is falsey,
so midnight is falsey even though it shouldn't be.
There's no good solution here, since we have a conflict between treating
time values as time values ("midnight is nothing special") and as numbers
("midnight == 0 which is falsey").
--> import datetime
--> mn = datetime.time(0)
--> mn
datetime.time(0, 0)
--> mn == 0
False
Apparently, midnight does not equal zero. Possibly because it should be
truthy. ;)
