Hi Martijn,
 
Thanks for ur mail, here the sample data as per u asked:
 
EmpNo        Date                Time
001         01/11/2008         09:12:00
002         01/11/2008         09:13:45
002         01/11/2008         13:11:10
001         01/11/2008         13:40:00
002         01/11/2008         14:01:22
002         01/11/2008         14:41:20
002         01/11/2008         18:21:22
002         01/11/2008         18:41:40        
 
But note that first time will be an entry time of an employee and his next time will be his exit time again entry time and again exit time for an employee for each day.
 
(I am not waiting for anybody's spoon fed answer but for a hint to get total time period for each emloyee for each day,nothing else.)
 
Regards

One date and one time?

Can you give sample data as to how you would like to calculate this then?
