Hello,

we port currently the FreeBSD timecounters to the RTEMS real-time 
operating system.

https://devel.rtems.org/ticket/2271

On FreeBSD the uptime starts with one second. On RTEMS the uptime starts 
with zero seconds. I would like to preserve the existing behaviour and 
it would be easy to adjust kern_tc.c accordingly. The problem is that we 
also use the FreeBSD network stack and it uses for example 
(microuptime()). Has a uptime value of zero a special meaning inside the 
kernel so that we must not start at zero?
