title: How to return current date in a different timezone in PostgreSQL
body: <p>I'm working on an application which uses Eastern time with a database set to Pacific time. This has been causing some issues, but we're told that it can't be any other way, so we just have to work around it. </p>
  
  <p>Anyway, one of the things I'm having trouble with is getting today's date. Since the database is in Pacific, if I ask for today's date using <code>current_date</code> at, say, 1AM, it'll give me yesterday's date. I've tried setting timezone and adding/subtracting intervals, but it never seems to work the way I expect it to, and I'd rather not have to do extensive testing at 1AM to get this to work. </p>
  
  <p>Is there a somewhat simple way to return a DATE for today's date in a given time zone in PostgreSQL? </p>
