On the other hand, a while back I remember looking at a number of date 
parsing libraries that clearly weren't going to be able to handle 
milliseconds in RFC 3339 / ISO 8601 formatted dates.

At the time, I recommended for the project I worked on that we never 
generate such dates with the millisecond format.  It wasn't critical 
that we used them, so it was an easy decision for us to discard them.
