Dick asked,
What I am looking for is a way to display Local Time (MST) and Zulu (GMT)
time in a small (6 X 8 or similar) package. There must be two displays
and
both lock up to NBS.
Has anyone seen such a thing ?
Might not meet all your specs, but MFJ may have something:
Here is another one, Cost $0.99
https://itunes.apple.com/us/app/utc-clock-pro/id512628478?mt=8
There must be 1,000 of these. If you don't have an iPhone buy a $80
Android tablet and get a free World Clock display for it. The time will
be as accurate as any of those Atomic Clocks and perhaps
.. or program your own, like a variant of this one:
http://www.satsignal.eu/raspberry-pi/DigitalClock.html
Standard TV output, so choose your display size, and it's NTP-synced to (on
that particular Raspberry Pi) a few microseconds.
Cheers,
David

The NavSpark project on Indiegogo has been mentioned here already, but I just
wanted to note that (apparently at my request) today they announced the design
was modified to include a timestamp function on external trigger input.

You can do a lot better than 5 ns these days if you want to spend some money.
Some low(er) cost alternatives:
5335 counter running GPIB. The counter should be below $150 and it should get
you to 1 ns or so.
5334 counter also running GPIB. A bit
Fellow time-nuts,
In a discussion it again re-occurred that we needed examples of how
leap-seconds is indeed is inserted into the local timezones at the UTC
midnight.
I think I recall that the Tokyo stock exchange was closed during the
leap-second for instance. Stuff like that.

This is of interest to me however I wonder is there anything in the code
that is tied to this specific 8051 derived processor? I have a number
of variations some going all the way back to the original Intel 8751s
and wonder if one might be used in place of the processor you used. I

Thanks anyway,

Paul,
If you use a different 8051, particularly one that comes from another
vendor, things like the UART, ADC, timers, watchdog, the clock and port IOs
are likely to be configured and addressed differently because most vendors
have their own peripherals different from the original Intel (or
Does the OP want to buy or build ?

Hi,
For a low cost startup have a look at a picPET
http://www.leapsecond.com/pic/picpet.htm and TimeLab

Less than $10 including shipping!

As much as I'm fond of my picPET it has 400 ns resolution and not intended to
replace a 5 or 10 or 50 ns TIC (which is what the OP asked for).

Tom,
Do you know of any other PIC projects that get a greater resolution? I was
thinking of doing something with a dsPIC33 running at 140MHz or greater, but
I'm not sure I want to devote the time to if it's it's been done.

Hi Bob,
It's pretty easy to get a tiny PIC or AVR down to 50 ns, so to me the next
sweet spot would be 1 or 2 ns. A couple of us are trying. Contact me off-list
re the dsPIC33.

Hello Time Nuts,
I hope everyone doesn't mind - I did get a few responses to this - but
still no manuals have made it my way.
I just wanted to resend in case someone does have them -and- I am able to
arrange getting my hands on them in a timely fashion.
Thanks and Best Regards,
John
