How to find out GMT offset value in android

Question

How to find out the values of GMT for user for example it is +05:30 for India. How do calculate this +05:30 value in Android ?

I need this because I am using a java library in my app which has a function with this +05:30 field and I want to generate this field by calculation so that I wont have to fill up individual values for countries.

This is what works awesome

   public double getOffset(){
        TimeZone timezone = TimeZone.getDefault();
        int seconds = timezone.getOffset(Calendar.ZONE_OFFSET)/1000;
        double minutes = seconds/60;
        double hours = minutes/60;
        return hours;
  }
