Yes, definitely baking time depends upon the pan size as well as the type of oven used. A good base of judgment would be to keep the cake undisturbed for the first 25-30 mins. That is do not open the cake door during this time interval. Once the first 25 mins are done you can keep checking the cake at an interval of 5 mins with a toothpick. If it comes out clean that means your cake is ready.
