How can we use Timers in PL/SQL?. Can we use?

In Forms, we are using timer using Create_Timer command,
When-Timer_Expired trigger will fire after whatever we have given time duration while creation of timer.

Same process I want to do in PL/SQL. Is it possible in PL/SQL? and How?. Anybody help to give command in PL/SQL.
