After reading the John Resig post about javascript time accuracy, I decided to make a simple IE wrapper that expose throught the window.external interface an high resolution timer for testing IE Javascript performance
The project is a very basic .net 3.5 window form project written using VS 2008 express,
it will require .net 3.5 installed.
I released the project on codeplex, you can found it at http://www.codeplex.com/IEJst
