change date process maker to persian date ( jalali

I want to change dates shown everywhere in processmaker to another format(Persian calendar). I have my custom class to format dates. What is the best way to override the default function which returns the formatted date? I just found the CurDate method in the G class. Changed it's returned value but dates are still shown in gregorian format. Is there any other method for formatting dates?

I prefer an OOP solution to override the default function instead of hacking the core, if possible.

Thanks.

For daynaform in PM2.x

1.Add jalali.js(Download) file to path \opt\processmaker\gulliver\js\widgets\pcal

2.Change the maborak file in path \processmaker\gulliver\js\maborak\core\maborak.js changed setup calendar like this

 Calendar.setup({
        inputField: id,
        ifFormat: mask,
        dateType: 'jalali',
        button: id + "[btn]",
        bottomBar: true,
        showsTime: showTIme,
        opacity: 1,
    });

maborak.js

3.In path\processmaker\gulliver\system\class.headPublisher.php and in function printHeader () you must add jalali.js file to header dynaform like this $this->addScriptFile("/js/widgets/pcal/jalali.js");class.publisher.php

For other place like current date top of the home page must in path processmaker\workflow\engine\skinEngine\skinEngine.php and in function _default() replace

$smarty->assign('udate', G::getformatedDate(date('Y-m-d'), 'M d, yyyy', SYS_LANG)) with

include_once("includes/inc.jdf.php");
$smarty->assign('udate', jdate('d F Y'));

For dynaform in PM 3.x

1.Add bootstrap date picker file(Download) to path processmaker\workflow\public_html\lib\pmdynaform\libs\datepicker\jalali
