How to get the query execution time

Question

Hi,
I am new to oracle and I am trying to get the execution time of a query.I tried the command set timing on and executed the query.But,the time it gives me is including the display of results.In my case,I ran a query against 50 million records and it is taking around 5 hours to display all the results.I like to know,how much time it take just to execute the query?Please help.
Thanks
Ravi.
