Can an atomic clock be wrong?

If you have an analog atomic radio controlled clock, it’s possible that the hands aren’t properly aligned. This could cause the clock to be off by a second or more even if it is receiving the atomic clock synch signal properly.

What is more accurate than an atomic clock?

New optical timekeeper is 10 times more reliable than caesium atomic clocks. A new timekeeper based on trapped strontium atoms accumulates an error of just 48 ps over 34 days of operation – making it 10 times more reliable than current caesium time standards.

Why is my atomic clock always wrong?

Low batteries are often the cause for weak reception. Relocate the clock. … If your clock did not change with Daylight Savings Time (DST), make sure the DST switch on the back of the clock is set to ON. If your clock is off by increments of an hour, the Time Zone (TZ) is set incorrectly.

When you turn a radio controlled clock on, it will probably miss the first time code, so it usually takes more than one minute to set itself (sometimes 5 minutes or longer) depending on the signal quality and the receiver design.

Why is my atomic clock not working?

Try powering down the clock (unplug it or remove the batteries), then turn it on again to see if it synchronizes. If the clock uses batteries, check them and replace if necessary. If the radio controlled clock is a desk top unit, try rotating it 90 degrees.
