"Put the clocks forward/back" is an expression used when moving the time on a clock one hour ahead or one hour back. This is typically done twice a year for Daylight Saving Time. When we "spring forward" in March, we put the clocks forward by one hour. When we "fall back" in November, we put the clocks back by one hour. It's important to remember to do this so that your clocks are displaying the correct time.
