Feature request: NTPv5

[mdavids]

Has support for NTPv5 already been considered, or is it too soon? 🤔

[beevik]

It's not yet an RFC, so I think it's still too soon for this package. It's also a pretty significant change to NTPv4. It introduces a new on-the-wire message format and a number of extensions, many of which will need to be handled by the client.

Given that IETF drafts can change significantly (or die without approval) before they become RFCs, I will probably wait.

(I should add that it seems highly unlikely that this particular draft effort will die without approval.)

Understood - I just wanted to bring it up, because deployments are starting to appear in the wild:

Also; https://github.com/mlichvar/chrony-ntp5

Both incompatible with each other btw, because of different content in the 'Draft Identification Extension Field'.
