Does lots of stop and go traffic change average time to replace a timing belt?

Question : "I saw the Q and A about timing belts. My question
is a little different. I have a 1999 Honda Civic. It has about 25,000 miles on it. I am being told that I need to replace the timing belt at 5 yrs. I live in Az and drive in stop and go traffic 90% of the time. Your answer to the previous question seemed to be that mileage, not time, is the deciding factor. That reader had more miles and only 2 years. I know if that belt breaks I am in big trouble but do not want to have to pay to have it
replaced before I need to."

Honda recommends the 1999 Civic (EX) timing belt be replaced at 105,000 miles. At an average of 15,000 miles/per year, that would translate to 7 years
(severe service interval).

Based on that, I would be recommending it at 105K or 7 years, but not earlier.
