----------------------------------------
There is an error in the Ruby-documentation of instance method #rfc3339 of class DateTime (eg. Ruby-version 2.1.5)

rfc3339() is actually equivalent to strftime(‘%FT%T%Z’)...
... and not, as it says in the Ruby-documentation, to strftime(‘%FT%T’).

See
http://ruby-doc.org//stdlib-2.1.5/libdoc/date/rdoc/DateTime.html#method-i-rfc3339
