The system clock running backwards…

While reading this mail written to the XEN – Users – List (virtualization on linux):

” I’m using a NetBSD 3.1 dom0 with Xen 2.0.7 (so far as I know, the latest
supported combination for the NetBSD platform).

Linux domUs have their logs fill with messages like this:

May 8 02:01:39 debian kernel: Timer ISR: Time went backwards: -316000
131542680000000 9684000 131542690000000
May 8 02:01:39 debian kernel: Timer ISR: Time went backwards: -277000
131542680000000 9723000 131542690000000

They come in different amounts, sometimes a handful, sometimes hundreds.
Over the space of a day or two, the logs swell to gigantic sizes.

I have been googling this for a while and it seems like I am the only
person in the universe to experience this after 2005. So apparently time
really has gone backwards – about two years’ worth.”

Now, i`d become REALLY worried, if some system would be doing that…

Remember the famous ‘Vaxorcist’ – tale?
Perhaps seen the ‘the exorcist’ – movies?

Wondering about systems becoming … strange?

Then this is for you

And I really sometimes wish for a bucket of holy-water when trying to figure out why a Windows server does ‘strange things’…
