I actually built one from an Arduino before. It's accurate within
milliseconds (which is enough for JT65), but I'm sure it could be made
better. (Source code at https://github.com/tmiw/arduino-ntpd if interested.)

I guess I have never understood why a clock on a radio was important. I guess
unless you use it for automatic wake up or something. But, the one clock I

Doing a little research I found a 32.768KHz surface mount crystal in the Newark

It

The accuracy is 20PPM, which equates to about 10 minutes/year. Since

I, for one, use the KX3 clock readout every time I'm on a summit in subzero
wind chills and my wristwatch is buried inside my heavy parka. Paper and
pencil logging is hard enough in adverse field conditions, but having the clock
right on the face of the KX3 helps a lot! The KX3 clock

Not sure how all this commentary on computer time applies to the
topic title. My KX3 keeps perfect time since I did not buy the
battery charger...no clock! My $12 wrist watch has about 1
second/year accuracy.
The K3 clock drifts over a week or so, but is easily corrected using

For the very time-obsessed, build and operate your own GPS-controlled
NTP time server as described here:

Yes, I admit, I have one of these serving network time here in my shack
or laboratory as my 8 year old son calls it. :)
Mine will drift a few minutes over a few weeks, but I do agree that 4200s
in one week points at a problem somewhere.

Actually ... atomic clocks such as the UTC one hanging on the wall of
my shack [that I won at radio club raffle] don't poll 10MHz. They
listen for WWVB on 60KHz, which mine hears only at night here in CA.
WWVB broadcasts a continuous IRIG-H time code with a somewhat obscure AM
modulation
The KX3 Utility could estimate the clock adjustment, if it is the only thing
that sets the clock. It knows the time it was last set and can measure the
drift.

In Windows Vista or later, you get a conforming implementation of NTP. Earlier
Windows versions are broken, even though I was using NTP with no problems

Even the native Win7 implementation is defective, updating only once every few
days and not using the differences to make corrections between updates.
Since I run HRD (running 24/7) and it has an NTP client in the DM780 program, I
use that. But I will look at what the others have posted too.

Try this:
1. Start the *Registry Editor*
2. Go to *HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet
On a Mac, open System Preferences, click on the Date Time pane, and check the
box for Set date and time automatically.
On Unix, read the appropriate RFCs and man pages. For extra credit, search the
web for ntp groper and see what I was doing twenty years ago.

Your deviation appears to be WAY off! Something else must have caused this

E.g., it has probably been a couple months since I reset my clock and it is
about 30 seconds fast now. Still annoying when you need it to be precise.
But then, Don has a
