In email to the XML Schema comments list on 5 September 2008
(http://lists.w3.org/Archives/Public/www-xml-schema-comments/2008JulSep/0135.html),
Peter F. Patel-Schneider raised the following issue (among others):

  1/ Time instants

  1.1/ Derived type for time instants with a required timezone

  The W3C OWL WG is determining how to use XML Schema dateTime values
  from the last call working draft [2] in OWL ontologies. The main
  problem the WG faces concerns dealing with dateTime values that do
  not have a timezone. The LC draft puts these values on a single
  separate totally-ordered timeline that is only partially ordered
  with respect to the absolute timeline.

  For the purposes of reasoning in OWL, it is much easier to deal with
  dateTime values where the timezone is present. Such values can be
  converted to single time points (using timeOnTimeline) and a
  complete order determined from the time points.

  The WG requests that a derived XML Schema datatype for dateTime with
  a required timezone be added to the XML Schema datatypes spec.
