Hi!

Just subtract the start time from the end time:

A1 = start time = 7:30 AM
B1 = end time = 5:45 PM

Format the cell as [h]:mm

=B1-A1

Returns 10:15

If the times might span past midnight use this formula:

A1 = start time = 10:00 PM
B1 = end time = 3:20 AM

=B1-A1+(B1<A1)

Returns 5:20

I have two fields "start time" and "end time" for tracking my time on
projects. on each line next to those fields i'd like to add a "total"
field that automatically calculates the total time in hours and
minutes. I thought there might be a function for this already, but i'm
not finding it in the help files...any suggestions?
