From 13c1bcf2c1d5fbdca99cdddec726f822b68dddbc Mon Sep 17 00:00:00 2001

Subject: - Use time_uptime instead of time_second in data structures for  
 PF_INET6 in kernel.  This fixes various malfunction when the wall time  
 clock is changed.  Bump __FreeBSD_version to 1000041.

- Use clock_gettime(CLOCK_MONOTONIC_FAST) in userland utilities.
