A cordless telephone system includes a base station having a base clock indicative of the time of day, and a handset having a handset clock indicative of the time of day. The handset is synchronized to the base station. When power is lost in the handset or the base station, the unit with power detects loss of synchronization therebetween. Upon restoration of the power, the continually powered unit provides the power restored unit with clock recovery information for updating the clock of the power restored unit. The clock recovery information is generated in the continually powered unit by counting elapsed time when the loss of synchronization is detected. |
