title: Argument to give to .setNumberFormat() in order to display Timezone
body: <p>I have a google apps script where I copy the date of the day in a cell. I would like to set the format of the cell to see something like "22 Aug 2012 - 23:55 - PDT".</p>
  
  <p>I don't find a clear list of all the arguments I can give to the method .setNumberFormat(). I found <a href="http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx</a> but it doesn't seem to work with all arguments.</p>
  
  <p>From trial and error I managed to guess "d MMM yy - HH:mm" which best fit my purpose, but I would like to add the timezone at the end ( "d MMM yy - HH:mm - Timezone"). Any clue ?</p>
  
  <p>Thanks,</p>
