CLOCK SETUP OVER A NETWORK |
摘要 |
<p>The present invention provides apparatuses and methods for updating a target device from a clock device through a network. The clock device obtains a time value from a clock source and sends the time value to a target device. A node within the network determines a time delay, adjusts the time value in accordance with the time delay, and sends the adjusted time value to the target device. The node may determine a time delay from an internal timer or from a measurement message when adjusting the time value. The clock device may send a subsequent time update message to the target device if the target device does not acknowledge reception of a time update. The clock device may also send a time update message to a target device when a status change of daylight savings time occurs and obtain a subsequent time value from a clock source.</p> |
