Получить смещение часового пояса из имени часового пояса, используя Javascript ⇐ Jquery

I found many solution that gives Timezone name from offset value. But I have Timezone name and I want offset value for that. I tried setTimezone('Asia/Kolkata'), but I think their is no method like setTimezone.

example:
Asia/Kolkata should give me -330 ( offset )
