Report "My old bedside clock radio started gaining time on a regular basis then after a few months gave up all together. I bought a new clock radio which also gained 30-40 minutes a day, took it back and exchanged it for another - same result gaining 30-40 minutes per day. Took the clock to a friends house and l left it there overnight - worked perfectly, time spot on. Does this mean I have a problem with my electricity supply or is there some other factor that may be the cause?"
