使用 TStopwatch 记录

Created: November-22, 2018

最新版本的 Delphi 附带 TStopwatch 记录，用于时间间隔测量。用法示例：

uses
  System.Diagnostics;

var
  StopWatch: TStopwatch;
  ElapsedMillseconds: Int64;
begin
  StopWatch := TStopwatch.StartNew;
  // do something that requires measurement
  ElapsedMillseconds := StopWatch.ElapsedMilliseconds;
end;
