Detailed Description

A simple class for keeping track of elapsed time.

CH_XD::OldTimer provides the ability to measure the passage of wall-clock time within units of code, and relate multiple measurements in a hierarchical manner.

A timer can be started, stopped, reset and printed out. Multiple timers can be instantiated and related to each other hierarchically: a timer instance may have a parent and children. The hierarchical relationship is relevant only when printing out the summary report.

In parallel, the timers on each proc operate independently. Only the summary operations cause communication between procs.
