 Could this change have caused an error like this?  This morning my Ultra10
gave a bogus NTP time warning shortly after I booted my new sparc64-current
kernel:

 I saw the error on the console at 8:14 and a manual check revealed the time
was off by only a few seconds.  I restarted ntpd, without changing the time,
and it worked without error.
