Hi,

First off you need a properly formatted start and end date and time in the
cell so enter a start/end date in the format

10/11/2007 22:30
To make it look like your dates apply a custom format of
yy/hh:mm

With a start date in A1 and an end date in b1, the formula
=B1-A1 will give you the time spent on a project
This cell should be formatted as
[hh]:mm
