I buy two of these to replace we two Timex bedside clock radio . Whenever there be a power failure , the time would drift on the backup battery so eventually they display different and incorrect time . they also have to be adjust twice a year between Daylight Saving Time and Standard Time . we grow tired of this . I search far and wide for a radio-controlled alarm clock with a amber lead back-lit display that stay illuminate all of the time . I be unable to find any . this clock be close . it have a amber lead back-lit display that illuminate for a few seconds when the snooze bar be press . the alarm be fairly loud and progressively beep more the longer it alarm , a good feature . however , if the snooze bar be not press , the alarm stop and do not beep again for another 24 hour . the best part , though , be that the clock never have to be set , be always correct , and automatically change between Standard and Daylight Saving Time .
