If you are using pool servers, best practice is to specify at least four
(that's the reason for having 1., 2., etc., so that you can select four
different ones). That way, if one of the them goes rogue it will be
exlcuded from the time solution but you will still have enough for a

I have a frequent sync rate so time is rarely off more than 0.020s.
Dimension-4 is freeware and easy to setup.

I use D4 as well.
It synch's on boot and every 15 minutes thereafter.
The longer you leave the computer on the more accurate the system clock.
I just checked and the last synch adjusted the system clock by .006
seconds. The computer rebooted three days ago.
That's plenty good enough for me.
Gary,
Is there any chance that perhaps your firewall might be blocking the traffic on
that NTP port?
This thought was triggered by the fact that all your computers were having
problems. From what I’ve found on Google doing a quick search that NTP can use
port 123 (IMCP, which is also used
Yes.

I think the main point is that for the last several versions of Windows you

Having an accurate clock if you are using, or plan to use, the WSJT digital
modes with Windows, is highly recommended.
The average user shouldn’t be making changes to the registry, and there is no
reason why you shouldn’t use a third party utility program to have an accurate
clock; even if you

I don't care what name you use for the server, sooner or later it will
change, or go away.
The pool has a whole bunch of time servers, run by different
organizations. The people who run them can add them to the pool, or
remove them from the pool when

I strongly recommend pool.ntp.org, using the native NTP software on your

A list of public time servers is here:
http://support.ntp.org/bin/view/Servers/WebHome
There is a list of public, stratum 1 time servers, but please please do
not use them directly, unless you run your own
Windows before XP didn't have native NTP support.
In XP, right-click on the clock, then choose internet time and enter
2.pool.ntp.org as the server. Make sure the synchronize box is checked.
I'd expect later versions of Windows to be the same, but they probably
aren't.
