## Discuss

### S4

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

   I think this ties too strongly to an outmoded way of handling leap
   seconds.  It is widely documented by some cloud operators, for example,
   that "leap smearing" can be employed [1, 2].  A scheduler taking time
   from a leap smeared clock would never encode "60" at any time, nor
   should it.

   I think you can retain this MUST if you craft an exemption for schedule
   producers and consumers that have no other way of dealing with leap
   seconds.

   (Separately, I've taken a note to see about crafting some draft that
    might be a useful reference.)
