Calculating elapsed time
 

I would like to calculate the elapsed time in hours of 2 cells with the
format dd/mm/yyyy hh:mm:ss. The two cells represent the start and finish time
of a job and the elapsed time is 0x<infinity. Does anybody know how to do
this?

=B1-A1, format as [h]:mm or just[h]
(FormatCellsNumberCustom)

Thanks for your reply Niek but this doesn't work or I'm doing something
wrong. If you notice the cells contain more than just hh:mm and the dates are
not always the same.

Hi

Niek's suggestion works absolutely fine.
Are you sure you are putting the [ ] around the h in the custom format of
hh:mm?
It needs to be [hh]:mm not hh:mm.
The latter will only give the hours difference, as the calculation won't
roll past 24 hours.

Whether you use [h] or [hh] won't make any difference other than showing a
leading zero for number of hours less than 10.

Thanks Roger,

but I can't get it to workMaybe its to do with the format of the A1 & B1.
The formula in C1 is B1-A1 and I've formatted C1 with both [hh]:mm and [h]:mm
but neither seem to work. Here is an example of the format of the cells:

Cell A1: 17/10/2005 10:09:13 Cell B1: 18/10/2005 14:09:11 Cell C1: #VALUE!

Any tips would be greatly appreciated,
Regards,

Probably your dates are actually text. You can check with the ISTEXT()
function.
If so:
Format the cells as dd/mm/yyyy h:mm and re-enter the dates and times (F2,
ENTER)
