摘要： In an exemplary aspect, method, apparatus, and program products are disclosed suitable for clock offset determination. One method includes performing a number of exchanges of at least single bytes with another network node, where values of the single bytes are different for the exchanges. The method also includes capturing and storing timestamps for each of the number of exchanges performed on the network node. A second method includes capturing and saving arrival timestamps for each of a number of timing messages in a set of timing messages received from another network node. This second method also includes sending the timestamps to at least the another node in response to completion of the set of timing messages.

摘要： A computer system is arranged with a circular buffer that includes a piecewise linear map from a high-resolution counter arranged to maintain International Atomic Time. The piecewise linear map includes a current leg that is currently being used and also a future leg that will be used in the future. The future leg is computed while the current leg is still being used.

摘要： Disclosed are a method of and a system for synchronizing clocks in a coordinated network of computers including a multitude of processing nodes, each of the nodes having a clock and one or more neighbor nodes. The method comprises the steps of electing one of the nodes as a correct leader node; and each of the non-leader nodes adjusting its clock rate, based on messages exchanged with neighbor nodes, to remain synchronized with the clock of said correct leader node. In a preferred embodiment, the adjusting step includes the step of each of the non-correct leader nodes using a weight assignment mechanism that gives neighbor nodes that are closer to the leader node more effect on the clock adjustment than those nodes that are further away from the correct leader node.

摘要： A protocol for communicating with the timing facility used in a data processing network to provide synchronization is provided via the execution of a machine instruction that accepts a plurality of commands. The interaction is provided through the use of message request blocks and their associated message response blocks. In this way timing parameters may be determined, modified and communicated. This makes it much easier for multiple servers or nodes in a data processing network to exist as a coordinated timing network and to thus more cooperatively operate on the larger yet identical data files.
摘要翻译：通过执行接受多个命令的机器指令来提供用于与数据处理网络中使用的定时设备通信以提供同步的协议。通过使用消息请求块及其关联的消息响应块来提供交互。以这种方式，可以确定，修改和传达定时参数。这使得数据处理网络中的多个服务器或节点更容易作为协调的定时网络存在，从而在更大且相同的数据文件上更多地协作地操作。
