How does a clock that has been disconnected from power for any length of time know what time it is when it is reconnected to electricity?

Just your average alarm clock with no connection to the outside world; just it by its lonesome. i recently had a power outage for an hour and the clock powered back on and had the time exactly right…and had me very confused. Thanks everyone!

Are you sure there’s not a battery in there as well? Plug in alarm clocks usually have a spot for a battery in case of power outage.

Another thing that’s possible is if the power came back on at midnight or noon. Then it would show the correct time, albeit flashing but still the correct time.
