title: Converting Timestamp observable to YEAR-MONTH-DAY format for polymer Dart
body: <p>What the title states.  I am calling a cloud endpoint that records the submission time of a record as a Java Date.  When I call for the record form this endpoint it returns it to Dart as a timestamp which I have binded through polymer to a template.</p>
  
  <p>However the Java Date is hardly human readable to non-programmers and I need a way to convert this in polymer to something that looks decent.  Any suggestions??</p>
  
  <p>Thanks</p>
