How to get device time zone short name in Android

Question

I need to show the device current time zone in short form. (For ex: IST for India Standard Time).

Below method returns full name of time zone. (i.e India Standard Time)

public static String getTimeZoneShortName() {
    return Calendar.getInstance().getTimeZone().getDisplayName();
}

Below method gives the timezone in short form if I use it in a Java program. But it gives the output as "GMT+5:30" on Android.

public static String getTimeZoneShortName() {
    return Calendar.getInstance().getTimeZone().getDisplayName(false, TimeZone.SHORT);
}

I need to show only the short form of the zone. How do I do it in Android?
