Clock gains 5 minutes or more time over 30-45 days

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.

American mantel clocks will gain or loose 5 minutes in a week, that is considered normal. This article will help you to adjust your time using the pendulum.

No fix, other than replacing the time movement, which is a switch movement that can be purchased at several different clock part supply stores, catalogs, or websites.

Hold the 'Clock' button until the display flashes. It will first show the year, next press on 'Clock' with show the month, then the day, then the time. Use + and - to set your time and press 'Clock' again.

Don't expect this clock to set the time by itself. It is not an atomic clock.

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

Compute the difference in clock-speeds, namely 90 seconds per hour.
Convert the units of time: 30 minutes becomes 180 seconds.
So, divide 180 by 90 to get '2', namely 2 hours after the 6 o'clock "start" time, which makes it 8 PM.











P.S. There is at least one error in the above solution. If you truly understand the solution, make the necessary correction, and submit the corrected "homework" to your teacher.

well if that is an electronic clock this problem might be because of the fact that these clocks use electronic timing circuit which consists of capacitors and resistors which are used to maintain a constant current flow to the timing circuit and if this RC(resistor, Capacitor) combination has some issues the circuit will not function exactly it is meant for and you will either get gain or loss of minutes.

so it is best to see if you can figure it out or just switch the clock.

I've noticed that manually setting the clock forward or back by any number of minutes, results in the same time offset being displayed after unplugging - plugging back in. So, if it's 9pm and you set if 5 minutes fast (9:05pm). Then unplug it and plug it back in 30 minutes later (9:30pm), the clock will maintain your setting of 5 minutes ahead of the actual time (9:35).

I like to set my clocks 5 minutes fast, just to make me always think I'm running a bit late (sure, maybe I'm a bit crazy). But this "sticky" manual setting is kind of a nice feature in my opinion. I'm wondering if it's not intentional?

Anyway, just manually set it back to the real time, and it sho
