Take Your Time Puzzle

Hungry Horace woke up one morning to find that his only clock had stopped working because the plug fell out.

Horace didn't have a watch, telephone, radio, television or anything else to give him the right time. His nearest neighbor lived over 2 km away, and the only way to get there was by walking.

Later that day, Horace could be found sitting in his kitchen, looking at his clock, which was now working, and showing the right time. How did he do it?
