Hi,
I need to display a duration that could last several month.
I make a difference between 2 dates and I apply the format mm/dd/ hh:mm.

It works fine except that it displays always 01 for the month.
For axample
18/06/2009 23:03
22/06/2009 07:21
result = 01/03 08:17
where it should be 00/03 08:17

In fact Excel treat this duration as a serial date. In that case the minimun
value for the month is 1 for January.
Then the same problem is propagated in the chart that I make based on that
column value.

Any help is welcome
Eric
