Filing of revised return beyond the end of relevant ay

Dear All,

In case of revised return, the due date of filing it is within one year from the end of relevant assessment year. Say if case one  wants to file revised return for AY 2010-11, the due date for filing revised return is on or before 31st March, 2012. 

Now can an assessee file revised return for the AY 2010-11 beyond 31st March 2012 if he has ommited to include interest income and tds thereon in his return...?
