Calculate Date times excel

Question

What I am trying to do to calculated the difference between to datetimes:

2016-12-24 00:00

and

2017-01-03 00:00

I have tried several "DateIf's" variations etc but nothing seams to get me the right result

My last approach to this issue was =MIN(B2-A2) but the reuslt was a bit of 12:51:45

My expected output would be the right amount of time in between these tow dates posted above for example 240:00
