# Thread: Showing the same time!

1. ## Showing the same time!

Albert Einstein was standing on the station platform thinking about relativity when he noticed that he could see two station clocks. Each clock was digital, showing only hours and minutes.

He observed that the display on one clock changed to the next minute 10 seconds before the correct time, whereas the display on the other clock changed to the next minute 10 seconds after the correct time.

For what fraction of the day did the clocks show the same time?

PS: I have a solution to the puzzle, but I'm not sure of its accuracy...hence posting it here to see what comes from it!!!!

<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">Totally ignoring relativity, one clock changes 20 seconds after the other clock, so they display the same time for 40 seconds every minute. For two thirds of the day they display the same time.</span hide>

Yes....you are correct! (Nice explanation!)
