convert decimals into hours and minutes
Convert tracked hours and minute (Not referring to time of day but cumulative hours of work) into decimals.

The following is a succinct description of how Excel stores dates/times internally:
They already are decimals, from beginning of existence to deletion.
When they LOOK like times, they are just being displayed as such.
To see the decimal version, just format the cells to display in any number-type format you like. Or just General.
Since they already are decimals, you can do math with them regardless of their displayed appearance. So 5:14 am + 11:13 am = 4:27 pm, whether displayed as times, or as decimals.
