At the moment it's not good.

1. "01:03, southern hemisphere, should be equal to 00:01". I think this is incorrect.
2. "12:24" is not the same as "00:24" - if we are talking about the direction of the hour hand, then, I'm sure that this is still the same thing.

Worst practice. This solution will not work, for example, if all numbers are equal to 5.
