3.1.5.3 Time Units in CPU Histogram
The CPU Utilization Histogram facility can output .CSV files
containing system-dependent time units. For official compiles of POV-Ray for Windows, these units vary according to
the results of the windows QueryPerformanceFrequency() API call. A scaling value is derived from this to
prevent the values in the CSV file overflowing 32-bit integer precision (since the windows performance API returns
64-bit integers).
If you want to know what the actual value of the units in the CSV file is for your system, run POV-Ray for Windows
with the /DEBUG command-line switch and observe the value that is printed in the message window when the
program starts. On the author's system, this is 0.838096 microseconds.
