ZylTimer 1.27

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 15 milliseconds. ZylTimer is a thread based timer and due to this architecture provides a higher precision (1-2 milliseconds), 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. It is important to understand that the accuracy of timers is limited. Windows is not a real-time operating system (except Windows CE) and it is not reasonable to expect timers to handle exactly very small time intervals.
