Comment (by viboes):

 In http://www.boost.org/doc/libs/1_59_0/doc/html/chrono.html you can find
 the reference to the recomendation on which these tags arebased.


 "
  system_clock::time_point I/O is proposed in terms of UTC timepoints,
 strongly guided by ISO 9899:1999, Programming languages - C, ISO
 9945:2003, Information Technology - Portable Operating System Interface
 (POSIX) and ISO 8601:2004, Data elements and interchange formats -
 Information interchange - Representation of dates and times.
 "

 By not supported I mean that it is not a valid tag and so it will result
 on an error (std::ios_base::failbit) as any standard IO operation does. It
 works as the std::time_get facet.
 It could add this if this is of any help to you. I expected that the user
 was aware of how standard IO facilities work.
