Resolution in the Windows system is limited. Generally speaking no better than 1ms no matter what you do. THis is due to the way Windows actually manages time in the PC hardware.

*nix variants on PC hardware handle it very differently.

There were a number of discussions a year or so back centered around some physiological event timing using the DJGPP compiler. This may explain the problem further but sadly I don't think it will offer a solution.

There is some discussion here http://www.codeproject.com/csharp/highresclock.asp about higher resolution - to 100ns - I have never tried the technique or investigated it further. jdtoronto

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
