ABSTRACT:
A device (10) for automatically adjusting a device containing a clock (70) that derives its timing function from the frequency of an alternating current signal on a power line is provided. The device (10) includes a controller (15) that receives user-entered controls for adjusting the clock (70) and generates control signals in response to the user-entered controls. The device also includes a frequency changer (11) that responds to the control signals to increase or decrease the frequency of the alternating current signal applied to the clock (70) so that the clock (70) may be adjusted.
