I solved, but the solution is wrong, there is no 60th minute in analog clocks (test case 20). Do not try to use mod until they fix it.

This is just to confirm what Rafael S.T. Viera stated!

There is no reason to use mod at all when parsing the time. Treat 8:60 like 9:00.

Remove the '08:60:33' test case. Parsing timestamps is not the focus of this exercise, calculating the angle between the clock hands is.
