[time-nuts] Lady Heather 5 leap second video

2017-01-01 Thread Mark Sims 
Lady Heather's on-screen clocks "tick" when the GPS time code message comes in. 
 Most receivers send the time code message around  100-250 msecs after the 
actual 1PPS time.  A few (like the Z3801A) send it before the 1PPS time.  The 
Jupiter-T sends it around 1200 msecs after the 1PPS!

Heather applies an adjustment factor to the time in the time code message to 
compensate for the receiver message delay/offset.  If you don't specify an 
adjust factor (/tsx=msecs), it uses a typical value for the receiver.   
Normally the time in the digital clock is shown down to seconds.  You can see 
the (adjusted) time down to the millisecond with the "TM" keyboard command.  
The hand positions in the analog watch display have the receiver adjustment 
factor, it's just that the clock is ticking when the time code message comes in.

My video is there:

I am wandering, if anybody else noticed that LH 5.0 watch is little 
behind of some other relatively good time source ? On my video, you 
could see my own NIXIE (driving by its own GPS receiver), my hand watch 
(synched by WWVB), 'xclock' from my NTP machine and Internet time on the 
web.



To follow up my previous note about 'chronyd', Linux syslog has 
following:


Dec 31 19:00:00 dl145 chronyd[2555]: Adjusting system clock for leap 
second


And then its interesting log (tracking.log). Here we could see how 
'chronyd' did the alignment (see the last column)

Hi!

Trimble thunderbolt and direct on-screen capture with 1 fps from Lady 
Heather 5 running on Windows XP.


23:59:59 --> 00:00:60 --> 00:00:00

It doesn't do it beautifully anymore, like older version did:
