title: xml schema Timezone
body: <p>I received some xml data that includes a timestamp taken at midnight of the application's local time in the xml schema standard dateTime format (see <a href="http://www.w3.org/TR/xmlschema-2/#dateTime" rel="nofollow">http://www.w3.org/TR/xmlschema-2/#dateTime</a> for reference).</p>
  
  <p>The timestamp is: 2012-02-04T13:00:00Z</p>
  
  <p>Based on information I've been able to find, the relevant timezone is '(GMT+13:00) Nukualofa' which corresponds to the location 'Pacific/Tongatapu'. We are only supposed to be receiving data with timestamps that correspond to timezones/locations applicable to the contiguous 48 US states, so I am bewildered as to what timezone/location corresponds to the timestamp.</p>
  
  <p>My question is, based on a dateTime of 2012-02-04T13:00:00Z, what UTC timezone, location on earth, etc. does it correspond?</p>
