When should the timing belt be changed on a 2002 Peugeot 307 1.6 GLX petrol?

I just bought a 2002 Peugeot 307 1.6 GLX petrol with service stamps in the book, but no record of a timing belt change. The car is coming up for 75,000 miles and I am unsure whether the belt has been changed. Do you know what the intervals are?
At this age and mileage it would be wise to assume it has not been changed and needs to be. The cost may be one of the reasons why the car is being sold.
