Was just about ready to "can" our gas range that we've owned for 13 years and decided to investigate the issue related to long oven heat-up times.  Initially I thought the issue was related to the age of the oven, but after a little research, determined the likely cause was the igniter.  The most difficult part of the repair was gaining access to the igniter location. Actual change-out took less than 15 minutes.  Oven now heats-up in under three minutes, compared to over 30 mins previously.
