I have the following table (Staff_Events)

...
Start_Date TIMESTAMP,
End_Date   TIMESTAMP,
Period     TIMESTAMP,
....

and need to set Period to the time difference between End_Date and Start_Date.  
End_Date will always be later than Start_Date. (Enforce by on Insert/Update 
triggers.)

I know I can the get difference with DATEDIFF, but I need the result as a 
TimeStamp.

I would appreciate any help.  

Regards


Cornie van Schoor
