  * - `medium`: equivalent to `MMM d, y h:mm:ss a` for en_US locale (e.g. Sep 3, 2010 12:05:08 pm)
  * - `short`: equivalent to `M/d/yy h:mm a` for en_US locale (e.g. 9/3/10 12:05 pm)
  * - `fullDate`: equivalent to `EEEE, MMMM d, y` for en_US locale (e.g. Friday, September 3, 2010)
  * - `longDate`: equivalent to `MMMM d, y` for en_US locale (e.g. September 3, 2010)
  * - `mediumDate`: equivalent to `MMM d, y` for en_US locale (e.g. Sep 3, 2010)
  * - `shortDate`: equivalent to `M/d/yy` for en_US locale (e.g. 9/3/10)
  * - `mediumTime`: equivalent to `h:mm:ss a` for en_US locale (e.g. 12:05:08 pm)
  * - `shortTime`: equivalent to `h:mm a` for en_US locale (e.g. 12:05 pm)
