I put some time values in A and B
In C I use =B2-A2+(A2B2)
In D I enters some 'codes'
Made a Pivot Table with 'codes' as column headers
I use SUM of time but I had to format the Pivot Table cells with Custom
Format [h]:mm to get results in hours & mins (by default I got decimal days)
best wishes - hope I understood the problem

My spreadsheet has two columns with two different times, as follows:

Col A Col B
11:06 12:09

These columns are formatted as Time xx:xx:xx (although I really don't care
about seconds), 24H format. I want column C to show the difference
between
column A and column B, in minutes, not hours. My problem is that when I
use
a Pivot Table to summarize the sum of column C, as soon as column C 24
hours, it shows 00:10:00 (ie. 24:10:00) and then the sorting in my pivot
table gets all out of whck.

Sorry--I suspect this is simple but I can't seem to figure it out.

Thanks in advance

Don
