Excerpt
Excerpt In one aspect, a local clock to be synchronized is reset and counts an elapsed time since the reset. Substantially simultaneously with resetting the local clock, a clock value is stored from a clock on a source node, which can be any other node in the system. The clock value read from the source node is copied to the node to be synchronized and added to the elapsed time. The resulting summation is then stored in the local clock so that the local clock is synchronized to the clock on the source node. |
