Thanks for posting the reference.
Very interesting and useful. The clues they give sounds like enough 
information to do the Smartclock loop control things that they talk about.

Hi Brooke,

> HP had some way around SA that improved the timekeeping.

HP called it the "Smartclock Algorithm" and you can find some very basic
information about it here:

I have been trying months to find a reference on how it REALLY works but it
seems that this is one of the better kept secrets of HP.

Best regards

Ulrich
