Pass. What happens if everything is "noselect"?

Likely, yes, but it varies between computers, chip makers (under different
trade names), and BIOS makers. For best timekeeping, you want no clock

The offset went from zero, to approximately +1.2 milliseconds. As MRTG
can't plot negative numbers (it was designed for network throughput), I
add 3.0 milliseconds to the reported offsets before plotting, as the left
axis label says. So the range of the graph is +/- 3.0 milliseconds,
plotted as 0 to 6ms.

Thanks for the suggestion, Ron, but that software, like most others, needs
XP or higher. I actually use that program on one of my PCs, as it can
also be called from the command-line to defragment files or directories.
