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.
ZylTimer is a thread based timer and due to this architecture provides a real precision of 1 millisecond which is inevitable in time critical applications.
The standard TTimer component uses the SetTimer API function, so the interval is limited to 2147483647 milliseconds (about 25 days). ZylTimer is a thread based timer and the interval could be set even to hundred years if necessary.
