TimerService in EJB 3

Hi all,
I am reading EJB 3 Core Specification.
I have a question regarding stateful session bean.

In Chapter 4 section 4.4.1 and table 1 regarding Operations Allowed in the Methods of a Stateful Session Bean. In that table we see that Timer methods can be accessed inside business methods, afterBegin callback, and beforeCompletion callback.
However, in the next page, there is a statement like below

"The TimerService interface is unavailable to stateful session beans."

In my mind, Timer methods is only defined in TimerService interface. So at this point, what does "Timer methods" mean?

Regards,
Daniel

It's the javax.ejb.Timer interface, not timer methods of TimerService.

if we don't have access to Timerservice in stateful session beans , then why do we need Timer methods at all?.
