Real Time Clock Difference Approximation Method for Two Computers over a Variable Latency Network

Abstract

Describes an algorithm to approximate the difference in internal Real Time Clock (RTC) settings between two computers that are communicating over a network with variable latency. This information can be used to approximate the latency of any message in either direction, not just round trip messages as is commonly done. This method does not rely on a central time server, such as the Network Time Protocol, and only measures the relative clock settings between two computers - not the true time.
