Like all the other repliee's (is that a word?) so far, I can't say I have much idea what's going wrong. The kernel is supposed to keep track of the clock by itself, effectively by counting CPU clock cycles. The only thing that I can think of is that I once read about when you have the kernel getting interrupted a lot, the clock doesn't get updated regularily enough, so the kernel loses time. Have you looked into this? Try running procinfo -n1, and having a look at the irq listings; maybe one of them will be rising rapidly, indictaing a lot of interrupts. Anyhow, it's a though -rob -- I did not vote for the Australian government.
