They have not been implemented, have they?  They are not yet part of a 
standard are they?

Wherever someone may have speculated about them, I think that, until 
they become part of an adopted standard and/or are implemented, it is 
fair to call them a figment of someone's imagination!

I believe that we run out of bits in about thirty years.  It's clear 
that we will need more.  The need for a 32-bit timestamp is less than clear!
