A Primer for Web Performance Timing APIs

High-Resolution Time Introduction All of the metrics that participate in the Performance Timeline are able to provides timing data in sub-millisecond resolution, i.e. in DOMHighResTimeStamp, which is defined by the High Resolution Time specification [[HR-TIME-2]]. Monotonic Clock In early stages of design, our Timing APIs were defined in terms of wall-clock epoch times. Unfortunately, such times o
