Description
Provides a high-resolution stopwatch implementation.
Use TStopwatch to obtain access to high-resolution timers that can be used to monitor the time spent performing some operations. TStopwatch uses operating system-dependent functionality to gain access to high-resolution timers, if available; otherwise, the usual timers are used.
TStopwatch is not a class but still requires explicit initialization. Call the StartNew or Create method to initialize a TStopwatch value.
