I run my RTC on UTC so there's no need for adjkerntz ever to change it.
Even if it did it would have been set over 3 months ago, and it's pretty
unlikely that the RTC would still be accurate to 1 second.

As I mentioned in my follow-up it's actually being set every 30
minutes by the kernel. I was pretty sure that someone had worked on a
fix for this, but I wasn't 100% certain that it had been committed -
until I saw the sysctl.
