Hi,

Last week we presented the latest updates to the Chronos draft.

In a nutshell, Chronos is now defined as a watchdog, which
periodically monitors the NTP clock and only when a suspected attack
is detected does the Chronos algorithm take over, replacing the NTP
selection and combining algorithm.

We believe this approach resolves the concerns that were raised about
the potentially low precision of previous versions of Chronos.

We would highly appreciate feedback about the current version of Chronos.

Best regards,
On behalf of the Chronos authors.
