      I believe:
          ISO-8601 will become popular when software makes it is easy to use.
          ISO-8601 requires range and precision specifications.
       
       History
          IEE-754 was an instant success it had details on range and precision.
          IEE-874 total failure and had not details on range and precision.
          IEE-754-r, every language is rushing to support it.  It provides detail missing rom IEE-874
       
      Supported by
       

      Standardization is important. 

      A program or a database is ISO-8601 compliant if the date/time is:

      Do you see no problem with this?

       

      There should be a standard!

      Eliminate the problem of Big “T” and little “t”

      Eliminate the problem of a comma “,” or a stop “.”

      Eliminate slow parsing, fixed format.

      Fractions of seconds can be any size, it is terminated by a “Z” “+” “-“ or a blank.
