A METHOD FOR AUTOMATICALLY UPDATING A PERSONAL COMPUTER SYSTEM TIME CLOCK OVER A TELEPHONE LINE ABSTRACT The highly accurate time stamp sent by the local phone company in FSK data streams such as the caller identification (CID) data stream is used to automatically update the PC system clock each time an FSK data stream is received. The telephone system transmits a data packet to the personal computer immediately after ringing the telephone. Data in the data packet represents the time of the telephone system's clock when the data packet was sent. This data, after being received by the PC, is decoded and then used to update the PC clock. Finally, a user interface is provided that allows the user to enable or disable the automatic updating of the PC clock.
