nptd not changing time.

[Kelly Martin <kellymartin_(_at_)_gmail_(_dot_)_com>]

I'm running ntpd on OpenBSD 3.6-release with default config. The
daemon is running and finding a big time difference, but it's not
changing the time. Here is a partial log entry:

Dec  2 11:39:59 Jesu ntpd[20331]: adjusting local clock by -566.282920s
Dec  2 11:44:02 Jesu ntpd[20331]: adjusting local clock by -565.378171s

Is ntpd not changing the time because it's already off by such a wide
margin (almost 10 minutes)? I don't understand the "now invalid" and
"now valid" messages, above.

I searched the archives of this list, and found someone who said (1)
that ntpd tries to set the correct time when it's first run, even when
there's a big difference, and (2) that perhaps rdate should be used
the very first time, if there's a big difference. Maybe this is
required -- but if that's the case, why the log entries, above?

I've read the manuals for ntpd and ntpd.conf, and there's nothing that
applies to this problem.
