// % note 1: Uses global: php_js to store the default timezone
|
|
// % note 2: Although the function potentially allows timezone info (see notes), it currently does not set
|
|
// % note 2: per a timezone specified by date_default_timezone_set(). Implementers might use
|
|
// % note 2: this.php_js.currentTimezoneOffset and this.php_js.currentTimezoneDST set by that function
|
|
// % note 2: in order to adjust the dates in this function (or our other date functions!) accordingly
|
|
// * example 1: date('H:m:s \\m \\i\\s \\m\\o\\n\\t\\h', 1062402400);
|
|
// * returns 1: '09:09:40 m is month'
|
|
// * example 2: date('F j, Y, g:i a', 1062462400);
|
|
// * returns 2: 'September 2, 2003, 2:26 am'
|
|
// * example 3: date('Y W o', 1062462400);
|
|
// * returns 3: '2003 36 2003'
|
|
// * example 4: x = date('Y m d', (new Date()).getTime()/1000);
|
|
// * example 4: (x+'').length == 10 // 2009 01 09
|
|
// * returns 4: true
|
|
// * example 5: date('W', 1104534000);
|
|
// * returns 5: '53'
|
|
// * example 6: date('B t', 1104534000);
|
|
// * returns 6: '999 31'
|
|
// * example 7: date('W U', 1293750000.82); // 2010-12-31
|
|
// * returns 7: '52 1293750000'
