Is it possible to turn back the clock?
Yes, it is!
Most residents in the USA, Europe, and several other countries across the world will turn their clocks back and get an extra hour of sleep on Sunday morning. That’s because at 2 am, clocks will move back one hour as daylight-saving time starts.
The practice was first implemented during the World War I, when Americans began setting their clocks back as a way to save energy. After being repealed for a few years after the war, daylight saving was revived again in 1942 during World War II.
Congress passed the Uniform Time Act in 1966, which formalized the start of daylight saving time on the last Sunday of April and the end on the last Sunday of October.
TO TURN BACK THE CLOCK
this expression has also metaphorical meaning… it means to return to, or to remember the past.
Example: ”I wish I could turn back the clock 20 years and be young again”
