Delphi includes a helpful unit called System.Diagnostics, which implements a TStopwatch record. It allows us to measure time events with a better precision than 1 millisecond and has a pretty exhaustive public interface, as shown in the code fragment below:
type TStopwatch = record public class function Create: TStopwatch; static; class function GetTimeStamp: Int64; static; procedure Reset; procedure Start; class function StartNew: TStopwatch; static; procedure Stop; property Elapsed: TTimeSpan read GetElapsed; property ElapsedMilliseconds: Int64 read GetElapsedMilliseconds; property ElapsedTicks: Int64 read GetElapsedTicks; class property Frequency: Int64 read FFrequency; class property IsHighResolution: Boolean ...
