Seems that the current ntp that comes in openbsd's port didn't like
the leap second at all.  It is now ~1.5 hours after the leap second
and the time is royally messed up, showing a ~500ms offset from both
new and old UTC scales.

If this isn't a wake-up call for keeping the kernel on some simple,
monotonically increasing scale then I don't know what is.
