Can't you combine a few Internet pool NTP servers with a local 1PPS source? The Internet servers will "name the seconds".
Also if you really need a Motorola Oncore you can buy them for $20 on eBay. There is no shortage. I paid $18 with free shipping for a UT+ I run the UT+ and leave the Thunderbolt powered off most of the time because the power used by the TB is so high compared to the very modest power draw of the UT+ On Sat, Dec 27, 2014 at 10:05 PM, Mike Cook <[email protected]> wrote: > I have had a look at the NTPns package and I don’t think that you will be > able do what you want without something naming the seconds.
