// note 1: - code more compliant with developer guidelines
// note 1: - for implementing PHP constant arguments look at

// 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'
