//////////////////////////////////////////////////////////////////////
//
// HighTime.h: interface for the CHighTime class.
//
//////////////////////////////////////////////////////////////////////
//
// CHighTime and CHighTimeSpan are two classes for high resolution time
// The range is +/-29000 years and smallest step is 0.1 microsecond
// They works like COleDateTime and COleDateTimeSpan.
// I wrote these because MS could not write working time classes
//
// Author: Hakan Trygg, h.kan@home.se
// Classes are not to be sold for profit.
// Please send me a mail if you find it useful and using it

// Revision history: 
// 1.0 : 12 Jan 2000 : /HT : Created
// 1.1 : 19 Jan 2000 : /HT : Made it possible to use classes without MFC
//
// Modified by Hans Dietrich to add Unicode support.

I attended St. Michael's College of the University of Toronto, with the intention of becoming a priest. A friend in the University's Computer Science Department got me interested in programming, and I have been hooked ever since.

Recently, I have moved to Los Angeles where I am doing consulting and development work.
