>Description:

When sysctl changes kern.rtc_offset it tries to cover up it's traces,
but not good enough: the "start" time of already running processes is not
fixed up.

(yeah, Perry said the current handling is insufficient ...)

>How-To-Repeat:

On a machine with /etc/localtime != UTC and rtclocaltime=YES in /etc/rc.conf
check the output of "ps -axuk start" - and wonder why kernel threads are
sorted "wrong".

>Fix:
On write to rtc_offset, walk the process list and adjust the start field?
