 * You might want to display or query based on the current day/time. 
 * The date() function is great for that, EXCEPT it uses the server's
 * timezone, which in my experience is typically GMT (six hours ahead
 * of me here in Texas).
 * 
 * WordPress lets you select a timezone in Settings > General, so let's
 * use that instead!
 * 
 * For information on formatting date/time (the first parameter), see
