Hi Tom,
and since it looks like you will probably needing additional help with
understanding and using date and time suggest you look over
http://www.mvps.org/dmcritchie/excel/datetime.htm

You might also keep the format [hh]:mm or [h]:mm
in mind to keep hours from overflowing into days when
you add up a column of times.
