The problem is that the time zone specification is ignored by the reader. It's ignored by the reader because there is no way to set it on a DateTime. Dart's DateTime objects currently exist only in either UTC or in what it thinks is the local time zone of the machine. Merging this with extending and specifying the format for what can be parsed in DateTime creation.
