title: Create date of a specific weekday two weeks before the current week
body: <p>I'm trying to create a SQL statement (in <a href="http://www.h2database.com/html/functions.html" rel="nofollow">H2 Dialect</a>) that creates a DATE which is 
  the tuesday in the "week-of-year" that is two weeks from the current week.</p>
  
  <p>For example, given CURRENT_DATE() returns 2014-04-23, the date that I want would be 2014-04-08, which is the Tuesday in the week that is two weeks before the week the Date "2014-04-23" is in.</p>
  
  <p>How can I express this with H2's Date and Time functions?</p>
