convert default calendar to Iranian calendar

Dear All
The default calendar that used in bonita portal is Georgian calendar. It shows the time like 02/21/2017 9:43 AM.
So, I want to change it to the Iranian (Jalali) calendar. I search the source code of community edition and in the following path “bonita-portal-js/main/assets/jqueryui/ui/i18n” I found the “jquery.ui.datepicker-fa.js” file.My question is how can I show the time like “چهارشنبه، ۳۰ فروردین ۱۳۹۶/۰۱/۳۰” format in bonita portal?
Any advice and suggestions will be greatly appreciated?

Best Regard

First of all, Does bonita portal calendar run on the client side or server side?
In assets/moment directory there is a javascript file, its name is “moment-with-locale” and there is locale configuration for Persian calendar. I think some trivial modifications needs to migrate to another calendar.
However, I don`t know how to use it. Please help me…
