          Summary:
          
          -   Karen presented the new note well.
          -   NTP Mode 6 draft (draft-ietf-ntp-mode-6-cmds) is ready for WG last
              call. No questions of comments.
          
          NTP WORKING GROUP
          =================
          
          NETWORK TIME SECURITY (NTS)
          ---------------------------
          
          Presenter: Daniel Franke
          No slides presented.
          Draft:
          https://datatracker.ietf.org/doc/html/draft-ietf-ntp-using-nts-for-ntp
          
          Summary:
          
          -   Addressed all the pending comments.
          -   The authors believe the document is ready for WG last call.
          
          Discussion:
          
          -   Karen: How many people have read the updated document?
          -   Very few hands raised.
          -   Harlan: Dave Mills has raised a concern about the lack of text about
              symmetric mode. DTLS will not necessarily work with symmetric mode.
          -   Franke: we will look into this and respond.
          -   Karen: we can proceed to WG last call, and address this during WG
              last call. We will start a 3-week WG last call next week.
          -   Karen: the NTP mailing list should be move to the IETF servers.
          
          MESSAGE AUTHENTICATION CODE FOR THE NETWORK TIME PROTOCOL
          ---------------------------------------------------------
          
          Presenter: Aanchal Malhotra
          No slides presented.
          Draft: https://datatracker.ietf.org/doc/html/draft-ietf-ntp-mac
          
          Summary:
          
          -   Algorithm agility is supported with NTP via the ntp.keys file which
              allows to specify the adopted MAC algorithm
          -   A section regarding test vectors are added.
          -   Some more minor changes.
          
          Discussion:
          
          -   Karen: looks like it is ready for WG last call. It will start this
              week.
          
          NTP CLIENT DATA MINIMIZATION
          ----------------------------
          
          Presenter: Daniel Franke
          Draft:
          https://datatracker.ietf.org/doc/html/draft-ietf-ntp-data-minimization
          
          Summary:
          
          -   There were some non-technical comments that we do not know how to
              address, and we are looking for another editor who will help us
              tackle these comments.
          
          Discussion:
          
          -   Aanchal: what does it mean to have another editor.
          -   Karen: the editor will be added to the author list.
          -   Suresh: these kind of personal issues are not very common. It is not
              necessarily required to have a new editor. The WG chairs can just
              take the decision how to proceed.
          -   Harlan: Dave argues that the document is not necessary, since it is
              very similar to SNTP. There may be an error in the document; the
              received timestamp gets sent back is data leakage, but that is not
              necessarily true.
          -   Franke: the document needs to be published, just to have a statement
              regarding the privacy and security issues.
          -   Aanchal: the document is necessary to emphasize the reasons for data
              minimization.

          bcp-05
          
          Summary:

          A YANG DATA MODEL FOR NTP
          -------------------------
          
          No presenter
          Draft:
          https://datatracker.ietf.org/doc/html/draft-ietf-ntp-yangwu-ntp-ntp-cfg
          
          Discussion:
          
          -   Karen: In the next interim meeting we will talk about WG last call.
          -   Harlan: no one has implemented it yet. It should not be difficult,
              but still important.
          
          GUIDELINES FOR DEFINING PACKET TIMESTAMP FORMATS
          ------------------------------------------------
          
          Presenter: Tal Mizrahi Slides:
          https://www.ietf.org/proceedings/99/slides/slides-99-ntp-guidelines-for-

          draft:
          https://datatracker.ietf.org/doc/html/draft-mizrahi-intarea-packet-timestamps
          
          Summary
          
          Discussion
          
          Tal: as for suggestion of the right working group for this draft Daniel:
          this draft should also consider correct handling of the leapsecond
          Yokoov: suggests to place the draft to the TICTOC working group Suresh:
          recommends the NTP or TICTOC working group for this draft Dieter: ask if
          the control field can also contain information about the uncertainty
          associated with the timestamp. Tal: this should be possible. The control
          field already has a field called precision that might be used for this
          purpose Fabini: NNN
          
          TICTOC WORKING GROUP
          ====================
          
          TICTOC WG STATUS

          Presenter: Karen O'Donoghue
          Slides:
          https://www.ietf.org/proceedings/99/slides/slides-99-ntp-agenda-and-note-
          well-00.pdf
          
          Summary:
          
          -   The IEEE 1588 MIB was finally published as an RFC ??" RFC 8173!
          -   Awaiting author update on the Enterprise Profile draft.
          
          YANG DATA MODEL FOR IEEE 1588V2
          -------------------------------
          
          Presenter: Yuanlong Jiang
          Slides:
          https://www.ietf.org/proceedings/99/slides/slides-99-ntp-yang-data-model-for-
          ieee-1588v2-00.pdf
          Draft: https://tools.ietf.org/html/draft-ietf-tictoc-
          1588v2-yang-05
          
          Summary:
          
          -   The authors are looking for more feedback.
          -   The authors would like to ask the WG whether the draft is ready for
              last call.
          
          Discussion:
          
          -   Karen: it looks like we are ready for WG last call.
          -   Karen: we will inform the IEEE 1588 working group about the last
              call.
          -   Suresh: we talked in Berlin about whether this work should be
              published as an RFC first, or sent to the IEEE 1588 first.
          -   Karen: the IEEE 1588 working group does not intend to publish a YANG
              model in the upcoming standard edition. We will publish an RFC, and
              in the future it can be used as a basis for the YANG model of the
              IEEE 1588 standard.
          
          GENERAL DISCUSSION
          ------------------
          
          -   Suresh: looking forward, we need to think about the future of the
              working group, charter and name.
          -   Karen: we have been considering a joint working group for a while
              now.
          -   Suresh: we can postpone the mailing list migration until we decide
              about the working group.
          -   Karen: we can stay after the meeting and think about a draft
              charter.
          -   Daniel: there are other WGs named TIME and DIME.
          -   Yaakov: the ACE working group deals with matters related to time.
          -   Renzo Navas: in ACE working group we will need to address problems
              related to time synchronization. It may fit a general time-related
              working group.
          -   Tal: it would be great if in the future we could have at least one
              slide for each draft that is being presented.
