The draft is more about time scales than protocols used to sync them. NTP is mentioned largely in its use of UTC. PTP supports a variety of time scales so it doesn’t add much to the discussion. Joe > On Nov 8, 2019, at 8:24 AM, Stewart Bryant wrote: > > > >> On 8 Nov 2019, at 15:40, Joe

CBORbis defines an “Epoch-based Date/Time” here making normative reference to Posix time with a brief discussion of leap seconds, positive and negative values and number of bits. (I’m not familiar with

One of the more enjoyable aspects of the Bundle Protocol is how you can't reliably correct a misset clock on a bundle node by using the bundle protocol itself - because the bundles containing payloads commanding the time change could well be expired and discarded before being carried out, once

I think you are right, apologies. However, this subject is such a minefield that the wise thing to do is to have the section reviewed by someone from the NTP/TICTOC WG. - Stewart > On 8 Nov 2019, at 15:34, Burleigh, Scott C (US 312B) > wrote: > > I disagree. From Wikipedia: > > Unix time

Yes, there is a risk that systems will drift due to accumulated leap seconds without updates.We worked throuugh the details...  http://lloydwood.users.sourceforge.net/Personal/L.Wood/publications/wood-ieee-aerospace-2009-bundle-problems.pdf   but keeping time accurately and continuously

Hi Stewart, As responsible AD I like to add a bit here. Please see inline. The WG will still need to discuss how to address these comments. Regarding the "pre-allocation" of certain bits and code-points, I would tend to agree. I think one can put tham as reserved in this specification. And in

Unix time != the Posix time API. One is a time scale; the other is the interface to obtain potentially many different time scales. I dove into these issues here: draft-touch-time Joe > On Nov 8, 2019, at 7:34 AM, Burleigh, Scott C (US 312B) > wrote: > > I disagree. From Wikipedia: > >
