Need Help

Query:

Say i have multiple sheets dated 04/01/10 to 04/30/10, each contain names,
say A, B, C, D, etc... but these name does not appear in the same order in
each sheet. Now data is in time format in front of A, B, C, D, etc.

Eg. in sheet 04/01/10

A1 B1
A 1:00:00
D 1:53:00
C 2:45:00

like this data in other sheet till 04/30/10.

Now in a new sheet i want this data to be collated in time format in front
of the individual sorted in Alphabetical order. Also it should give me the
Sum of the data.

Is it possible and how?

Thanks in advance for the help!!!

Prashant.
