Apologies, Sometimes the threads get a little jumbled my end.

What's a good email client with quoting etc, I am using outlook 2010 at the moment...

I fired it up, ah ntpd v4.2.7p253 doesn't seem to recognise refclock 31 anymore which got a giggle out of me :)

I added the usual server 127.127.31.1 property into the config file but it never shows up on the list of peers.

So I have tried pps (driver 22)

One thing I noticed, no matter which PPS source I try, (acutime gold, rockwel, HP GPS) they always get marked false tickers!

I have removed the min/max poll tokens from the property and I will now leave it running to see if it pulls in. 

I did have to fudge time1 0.0480 to get offset down..

C:\Documents and Settings\Administrator>ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter

+ntp.brisbane. .ATOM.           1 u   55   64   67   31.316    0.897   1.929

as soon as I put flag 3 1 in the fudge I always get:  refclock_params: time_pps_kcbind: Unknown error: 45 

According to a reply to an earlier post that is because it is not implemented in NT. Oops.

Other than that, have a great Sunday!
