Hi,

Example here

http://coding.derkeiler.com/Archive/C_CPP/alt.comp.lang.learn.c-cpp/2003-10/1491 .html

ClockTime is calculated with EndTime-startTime
it is the real Time of execution
whereas ExecutionTime is the cpu time used

If you run several times the same work, you should have the same ExecutionTime
but the clockTime depends on other softwares execution.
