Digital clock gains time

There is no fix or repair. Unfortunately it is a disposable item

Question edited for clarity. Category moved to Clocks - Home.

Quartz digital clocks normally have no method of adjustment. The most likely reason it is gaining now is a failing capacitor or resistor. A voltage is applied to a quartz crystal and the electrical vibrations from it are translated into time. This article suggests there may be a 'trimmer pot' inside. They look like a short 1/4" block, or a circular device with a Bakelite screw slot in the middle. The need VERY small changes.

It you really want accuracy, buy a new Atomic Clock that is set automatically via a Time Server.

strange..... electricity runs in certain cycles.... maybe you need to check your electricity, or your wiring

I read the manual which said to depress the alarm button. That wasn't the right button but I found that depressing the button next to it, the DST button, that that fixed the problem.
Thanks.
