I’ve just returned from holiday after a week away and plugged my bedside clock/light back in and set the time. A few hours later, when I went to bed, I noticed the bedside clock was now showing an hour and 45 minutes slow. I reset the time again before going to sleep. In the morning, I once again found the clock an hour and a half behind. Does anyone know what causes clocks to lose time in this way? It was working perfectly before I went on holiday. Is it for the bin? Many thanks. M.
