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 1-2
milliseconds which is inevitable in time critical
applications. The OnTimer event is always fired in
time which is not available for the standard TTimer,
when there are too many messages processed.
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.
