title: PHP Echo Timezone based on GMT offset
body: <p>I have an application that stores GMT time data in a MySQL db like this: 2009-12-16 15:27:47.</p>
  
  <p>The user's timezone offset is stored in another column like this: -6</p>
  
  <p>The above timezone is GMT-6, which is CST. Is there any way I can echo CST (i.e. - date('T")) from the GMT offset data?</p>
  
  <p>Note: I should also add that the application global timezone is set using: date_default_timezone_set('GMT');</p>
