It is well known that a stopped clock gives the exact time twice a day, while a clock that gains or loses time may not be right more than once over a period of months.

My clever father adjusted his clock to give the correct time at least twice a day, while running at the normal rate.

Assuming he was not able to set it perfectly (a reasonable assumption) how did he do it?

Your Father removed the battery/springs/whatever from the clock,while he was running at the speed at which he normally runs(it is not specified that the clock is running at the normal rate,and besides,this is a trick question,eh?)
