OSX and Network Time

[Richard Kriss]

I have tried several times to use the network time sync option and
assume my ISP may not support Network time.

Anybody been able to use network time with Great Barrier Reef?

I just tried apple.com and got

"Synchronization Failed. Your NTP server may not be responding

apple.com is not time.apple.com

# host time.apple.com
time.apple.com has address 17.254.0.26
time.apple.com has address 17.254.0.31
# host apple.com
apple.com has address 17.254.3.183
# host apple.com
apple.com has address 17.254.3.183

Yes, that's why I suggested time.apple.com, not apple.com.

Periodically. By default the interval is between 2^12 seconds (i.e.
about 68 minutes) and 2^17 seconds (i.e. about 36.4 hours). Network
time setting uses the standard network time protocol, using (I think)
FreeBSD's ntpd. The interval is set up in /etc/ntp.conf, and no, I
don't know how it decides the exact interval to use. Looking at my
system log shows that I've recently synced up at these dates and times:

Aug 26 17:39:54
Aug 26 11:58:17
Aug 25 14:42:14
Aug 22 19:24:28
Aug 22 13:42:55
Aug 21 18:23:48
Aug 21 12:42:10

I haven't looked at startup items, but my last reboot was between the
two oldest entries on that list, and not close enough to either to
suggest an automatic sync at boot time.

Thanks.

New data on the time/date shaggy-dog problem. Based on the tips provided
I managed to get my time synced with the time.apple.com server. I had
the little box checked to use this option and everthing was working okay
until my ISP dropped the dialup connection. Like the bumper sticker
says, it happens. Mac OSX does not really warn your when the connection
has been disconnected and the time/date thing went crazy when it lost
sync. The date on this G4-450 went to December 1969 and that did crazy
things to my Entourage email program.

I had to changed back to setting the clock myself. BTW, I did check the
battery in the G4 and the voltage looks good.

My 17" iMac 800 loses a few minutes every couple of days, despite using
a time server and being connected via broadband 24/7. I do log out and
back in every time I use it, but if I log out at 0200 and log back in at
0900, it will have lost a few minutes each time. seems like the longer
the logout interval, the more the clock gets behind. Any suggestions?

Dick-

I suppose there are lots of time servers on the net. Another I've used is at
the Naval Observatory, tick.usno.navy.mil or tock.usno.navy.mil.

If you're running OS 9 or earlier, there is the "Network Time" Control Panel by
Pete Resnick. I have version 2.01 dated 1993, that works under OS 9.2.2. It
can be set up for various update options. I have a dial-up ISP, so it is kept
in the Apple Menu folder. That way it won't update the time unless I manually
initiate it.
