[NLRS] Sync your PC within milliseconds of real time

[Doug Reed]

I've been using NNTP/SNTP software to keep my PC's clock set right for
well over 10 years. For the last several years I've just been using
the "Internet Time" tab in the "Date & Time Properties" window under
Win XP. My computer is set to only check network time once a week, but
that seems adequate to me. I think it can be configured to check more
often, but I haven't checked.

The Dimension 4 web site claims Leo Laporte (TWIT.TV) recommends it,
and I'd accept that recommendation if I needed SNTP software. It also
has several features that would help in situations where time sync
must be done, even if the chosen time server is down. But I expect
that all later versions of Windows have some SNTP software built-in.
For Linux users, the ntpd driver has always been there.

On the other hand, the usual problem with SNTP and NNTP setting
software is difficulty in compensating for network delays when trying
to set the clock more accurately than half a second. But if you need
that sort of network time accuracy, then you should be looking for
software and hardware to set your local NNTP server using GPS for the
timing signal. That should let you set your clock within milliseconds
of actual time. Then all you need to do is set your Windows clock to
display it correctly.  :-)
