   What for? I consider all these schemes just as internal
   representations of UTC time stamps, chosen according to special
   needs and constraints. We would not have so many different
   internal representations if there was no need for them.

   For data interchange and external storage, We have the standardized
   and well-understood notation of ISO 8601 for time stamps
   with leap seconds, such as 2015-06-30T23:59:60.2Z. Every
   internal representation must be convertible to and from that
   standard. In my opinion, no other standard is needed.
