set the/(one's) clock(s) back
To adjust the time on one's clock(s) back by one hour to account for the end of daylight saving time. Don't forget to set your clock back tonight. We get to sleep in a little bit tomorrow! I hate having to set the clocks back every fall, it's such an antiquated custom.
