SOLM12 — TimeInterval output string formatter has incorrect formatting

Within SpacePython times.py TimeInterval _str_() function, the following lines are faulty:

hours = seconds / 3600
minutes = (seconds % 3600) / 60

Both of these variables should be integers (not floating point values)

These instead should be:
hours = int(seconds / 3600)
minutes = int((seconds % 3600) / 60)

Update hours and minutes calculations

In times.py, change:
hours = seconds / 3600
To:
hours = int(seconds / 3600)

And:
minutes = (seconds % 3600) / 60
To:
minutes = int((seconds % 3600) / 60)
