Frequently Asked Questions
How does an atomic alarm clock work?
An atomic alarm clock receives time signals from a radio station broadcasting atomic time. It synchronizes automatically to ensure the time is accurate to the second without manual adjustment.

No, most atomic clocks automatically sync to the correct time once plugged in. You may just need to set your time zone initially for it to adjust properly.
