Answer 1

>>> import datetime
>>> time1 = datetime.datetime.strptime("6:30",'%H:%M')
>>> time2 = datetime.datetime.strptime("7:30",'%H:%M')
>>> difference = time2-time1
>>> difference
datetime.timedelta(0, 3600)
>>> difference.seconds
3600
>>> "{:0>8}".format(datetime.timedelta(seconds=difference.seconds))
'01:00:00'
>>> "{:0>8}".format(datetime.timedelta(seconds=666777))
'7 days, 17:12:57'
