1996 Toyota Corolla Timing Belt replacement

Hi,
I have purchased 1996 Corolla DX car about 9 months ago. I would lie to know when am I supposed to replace timing belts for this car. Current reading is 99, 3XX. I have got the service records showing some belts were replaced year ago when it was 87, xxx miles. I am giving the details of the parts replaced by Toyota Dealer.

9996 Standard 60 CT 1 no 98$
99365-20970-83 30.70 $
99363-90630-83 V-Belt 8.38$
99364-20870-78 V-Belt 36.28$

Please advise me if the timing belt is already replaced ( if its in the above parts replaced).

If not, please advise me when I am supposed to get the timing belt change and what other service is due at the current 99, XXX miles.

Car is running smoothly with out any issues so far.

Thanks & Regards
Sriram
