Yeah, I had kept putting off upgrading to one of the fixed releases due
to the assumption that my area of Southern NH would be among the last to
get IPv6 switched on.  Wasn't until I started looking into why my
Internet performance had gotten so bad I remembered the bug (and why I
kept reminding my self to upgrade)

I'm more than happy to try to help out (which is why I joined the devel
list), but I'm more of the Sysadmin type than Developer (which is why
I've been lurking).

Ok, part of my issue was probably also that the clock was so far off, it
didn't want to skew to the correct time.
