» Calculating Total Time Worked on a

Problem:

Columns A & B contain the dates and times that a person signed in and out of work.
We want to create a new column containing the date and the calculated time that was worked on that day.

Solution:

Use the TEXT and TRUNC functions as shown in the following formula
=TEXT(TRUNC(A2)+(B2-A2),"mm""/""dd""/""yy"" - ""hh"" Hrs ""mm"" Mins """)
The above formula performs the desired time calculation and uses the TRUNC function to return the relevant date.
