//
// (1) How come we declared time, hours, minutes that way?
// (2) What is a legal time?
// (3) for, but not using incrementing, but as a while
// (4) Can we be neater/shorter?
// (5) why bother with while?
//     - syntactic sugar
// (6) Have we properly validated time?
//     - do we allow negative time?
//     - why did we not think of this?
