ZylTimer is a high resolution, long-term Delphi / C++Builder timer component which provides a higher precision than the standard Delphi / C++ Builder TTimer component. TTimer component which ships with Delphi / C++Builder uses the Windows Message Queue to generate the OnTimer event. Due to this approach it's impossible to get accurate timer intervals smaller than 50 milliseconds.
