That's what I did. But it can't work, if there's no server lines, I
_always_ got:

# /usr/sbin/ntpdate -u -b
28 Aug 11:21:35 ntpdate[10515]: no server suitable for synchronization

( is my own NTP server.)

And if I didn't remove the server lines, I can easily run the above
successfully. :-)

Any ideas?

Thanks, I just need not to synchronize. :)
