It hasn't happen to mine. It's been working great.
I have had two of them for years, and that never happens.
Do you live in the USA? I think it can only remember USA time zones.
Does it show that you are receiving the WWVB radio signal late at night? That is indicated by a radar dish symbol in the upper right of the display, just below the USA map.
If you aren't seeing that symbol, your clock isn't getting a strong enough signal to maintain "atomic" time synchronization, and will require periodic manual adjustment. You might try moving the clock around your room or house to see if you can pick up the radio signal. Might be tough if you live in an area surrounded by tall buildings. Try a location near a window facing toward Colorado, if possible.
