I have a spreadsheet with start and end times for people's working day,
in 24 hour format. So it will be 830, 900, 1030, 715 etc in the start
column and 1700, 1715, 1550 etc in the end column. I would like to do
a calculation on these times to work out for each person how many hours
are in their working day (including lunch and breaks). At the moment
Excel regards these as regular numbers, so I cannot do a calculation
like 1700-830 because it won't come out right. I have tried fiddling
with the cell format with no success. How do I do it?

Try "hh:mm" in place of "00\:00"
