Hello everyone.

Can anybody tell me if there is an ISO Standard that relates to the precision, repeatability, etc for these clocks. I'm sure I read something that mentions an ISO standard.

I love these clocks, by the way. I have built five and two are used in the house. My friends have built another three.

Well, the relevant ISO standard is ISO8601, but it's a standard for time/date format, not precision or repeatability. There are a lot of people who are devout fans of ISO8601, there's even a subreddit for it.

In terms of the timing accuracy, there's another thread here where someone compared the PPS output to some expensive alternatives.

Of course the serially-addressed display drivers have several orders of magnitude more jitter than this, but it's nice to know.

ISO8601,

Thank you. In spite of my wording, that is what I was looking for.

Much appreciated!!
