Hello time-nuts folk, Thanks for all the replies, I see now that it is nothing to concern myself with, and my curiosity is satisfied, much appreciated, you are true time experts! :) Good to see Lady Heather continues to be updated, thanks Mark. on 12/10/2017 12:36 you wrote: >

[time-nuts] NTP linked PC clock is slightly ahead of Lady Heather GPS time

Lady Heather's screen clock ticks when the time message comes in (which can be offset from the actual time in the message). Heather applies a receiver type dependent adjustment to the time in the message and then displays the time. If you enable the digital millisecond clock you will see that

Hello, According to that clock LH is lagging about 0.5 seconds behind... PC time matches it exactly, as close as the eye can tell. Thanks for the replies. on 11/10/2017 17:11 you wrote: > For those who are in Europe there is the PTB (Physikalisch-Technische > Bundesanstalt, the German

For those who are in Europe there is the PTB (Physikalisch-Technische Bundesanstalt, the German Federal institute of Physics and Technology) service to check the PC's time: On Wed, Oct 11, 2017 at 5:25 PM, Mike Cook wrote: > I have Win7-64 and my LH and

Re: [time-nuts] NTP linked PC clock is slightly ahead of Lady Heather GPS time

I have Win7-64 and my LH and system time are the same (with a very short delta of < 0.2s probably due to their respective window update time). I use the Meinberg disturb of NTP. My client’s offset from the paris observatory is less than a millisec. Maybe you should check your NTP status and see

[time-nuts] NTP linked PC clock is slightly ahead of Lady Heather GPS time

11/10/2017 12:24 Probably a simple answer, but I am curious as to why my PC clock which is set by NTP on Windows 7 64 bit OS is ahead of Lady Heather's time, locked to a Trimble Thunderbolt by about half a second (guesstimate..) I caught a screen shot of the discrepancy
