How do you add numbers that are not in time format? They are not in time
format as it is for addition purposes only i.e. If I worked 7 hours 1 day and
7.85 hours the next it should read 15.15 hours and minutes in total.
If using the time format it will read the results as time i.e. 15:15 in the
afternoon, this is the wrong result.

Any ideas?
