My Clock Gains Time

I have: SN 407030070PH Model # CKS2237 My clock constantly gains time - sometimes as much as 15 or 20 mins. I have moved it near a window and this did not fix the problem. How would you suggest this problem be fixed? Blessings, Brenda.

Cloc gains time

well without the make and model number I can only answer generally , most clock radios use the power line to sync the time base (60 hertz=60 seconds = 1 minute=60 minutes=1 hour) , but they use a internal time base generator when running on battery back-up (that's not so accurate) , I had one some time back that a customer plugged into a switched outlet (unknown to them) in there room and it did exactly the same thing it gained about seven minutes every day , me id check the outlet its plugged into to see if its on all the time (a quick test 4 this is to remove battery back up ) clock will then flash to be reset if you come back later to see it when the power was shut off

My clock is gaining time that is it is gaining about 10 minuts a day. what do I need to do

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.

Model CKS2237 Daylight Savings needs to be reprogramed

I have the same model, and I haven't found any sites that give a permanent solution. I did find a workaround for this model, which seems to fall in the "Group One" category on the following site. It is at least more of a one-touch solution (4x/yr) than manually moving the time forward/backward 4x/yr.

RCA alarm clock - RP3721 - crystal or AC for time?

They used to use crystals to help the timer ics to keep time but since the development of Micropros. all this is built in to one chip. Now they will use a resonator or a small crystal for the timing clock of the micro but nowdays the manufacture uses that clock to keep all in check. If your gaining time you probably are having problems with your ac duty cycle as this also keeps clocks in check.. This would not affect most devices but could be a problem. But of course a defective Micro could also cause this gain in time And probably is?? Now a battery backup is nothing more then a battery in line with the Microproccesors B+ terminal through of course a diode as well as a voltage limiter resistor to take over the B+ when the units ac supply is absent..
