The ftime function is described in a misleading way in the
"Microsoft C 5.1 Optimizing Compiler Run-Time Library Reference" ,
Page 308 for C Version 5.x and Page 217 for C Version 4.00.
The field millitm in the timeb structure that ftime returns is
described to hold the value of the fraction of a second in
milliseconds. The field contains three digits as described;
however, the last digit always is zero. Thus, the function returns
millitm incremented to the nearest one hundredth of a second.
Note also that this function uses the system clock to determine
the time. Since the resolution of the clock on PC's is about 1/18.2
seconds, the time function can not be more accurate than that.
