No, I have looked that those, they do not work for me as I need to be 
able to compate the value if 'ticks' with a value initialized from 'ticks'.
The problems is that 'ticks' is not 'exact'. So I cannot calculate it 
with the different between the boot time and the current time * a 
constant factor.

Any ideas? Might patching (adding it to) sysctl be a thing to consider 
or would that cause security issue's?

Thanks!
Jan
