Does anyone remember the name of this movie?

Hi, this has been bugging me all night. I saw something that reminded me of a movie that I saw when I was very little, and can't remember the name of it no matter how I search for it. It involved a young boy and an alien spaceship that could fly at any speed, and I believe he used it to travel through time? At the end his friends used fireworks to guide him back to his house. Sorry its a little vague, but I was really young when I saw it. Thanks for any help-
