  //      note 1: Uses global: locutus to store the default timezone
  //      note 1: Although the function potentially allows timezone info
  //      note 1: (see notes), it currently does not set
  //      note 1: per a timezone specified by date_default_timezone_set(). Implementers might use
  //      note 1: $locutus.currentTimezoneOffset and
  //      note 1: $locutus.currentTimezoneDST set by that function
  //      note 1: in order to adjust the dates in this function
  //      note 1: (or our other date functions!) accordingly
  //   example 1: date('H:m:s \\m \\i\\s \\m\\o\\n\\t\\h', 1062402400)
  //   returns 1: '07:09:40 m is month'
  //   example 2: date('F j, Y, g:i a', 1062462400)
  //   returns 2: 'September 2, 2003, 12:26 am'
  //   example 3: date('Y W o', 1062462400)
  //   returns 3: '2003 36 2003'
  //   example 4: var $x = date('Y m d', (new Date()).getTime() / 1000)
  //   example 4: $x = $x + ''
  //   example 4: var $result = $x.length // 2009 01 09
  //   returns 4: 10
  //   example 5: date('W', 1104534000)
  //   returns 5: '52'
  //   example 6: date('B t', 1104534000)
  //   returns 6: '999 31'
  //   example 7: date('W U', 1293750000.82); // 2010-12-31
  //   returns 7: '52 1293750000'
  //   example 8: date('W', 1293836400); // 2011-01-01
  //   returns 8: '52'
  //   example 9: date('W Y-m-d', 1293974054); // 2011-01-02
