Interesting, indeed. The mysterious #mirc helper comes at me again:

[19:39:17] <Zinob> oxicarus`: indeed the most common reason for this is due to the fact that the hardware generates Timer Interupts at regular intervals. And if windows is to buzzy it will dissregard these as it wel.. dont have time for them.
[19:39:53] <Zinob> hence the clock of slower computers has a tendancy to drift backwards slowly
[19:40:18] <Zinob> And the time accounting of running processes get kinda FUBARed

Would be awsome if we could just "sum it up" to that it's like that, but still, would be awsome if Khaled could bump in here and explain his $uptime(system) function so we got clue wink
