All,

(context: prompted by my question in TVR)

I see that in draft-ietf-netmod-schedule-yang Section 4 it advises:

   *  The second for date and time values MUST have the value "60" at
      the end of months in which a leap second occurs.

but I fear this is not sufficient.  A scheduling entity in a data center
taking its time from a leap smearing [1, 2] source would probably not know
that this needs to be done, and its notion of time would be
subtly different over a span of (typically) 24 hours prior to the leap
second.

Would it be possible to also include some time reference that doesn't have
to deal with leap seconds, like TAI [3, 4]?
