how do you set the timers?

I was baking on my caloric heritage series gas stove when I noticed my clock wasn't right. so i turned it to the right time and noticed the knobs on the right for Stop adn Start were off so I turned them so they pointed straight up on 12 and my oven went off. I have no papers or instructions with my stove. can you please tell me how to set the timers or where i can get instructions...thankyou
