[SOLVED] How do I calculate time durations over numerous dates

I am trying to enter data that was collected on different dates/times and
calculate the duration of the entire data collection. How can I enter the
dates and time such that I can calculate the duration? I am using Excel 2000

If you enter them as standard time, such as 09:15:30, then just subtract
them to get the duration, and format that as time also.

I've got that, but what about including different dates? I tried formatting
the cell such that the date is also part of the entry but then I can not
subtract them.

Why not? It will still have a valid value, it just differs how you present
it.

One way would be

=INT(A2-A1)&" days, "&TEXT(MOD(A2-A1,1),"hh:mm:ss")

Format the result as Custom [h]:mm otherwise the sum will "tip over" each
24 hrs
