>Description:
The man page for sysctl (section 3 and section 8) state that kern.rtc_offset is not settable. 

Therefore, I'm not sure if this is a functionality bug, or a documentation bug:

bugs# date
Wed May  4 23:19:17 MST 2005
bugs# sysctl -w kern.rtc_offset=420
kern.rtc_offset: 0 -> 420
bugs# sysctl -a | grep rtc
kern.rtc_offset = 420
bugs# date

>How-To-Repeat:
As above.
>Fix:
Either fix the documentation or the code. Not sure which.
