How to get the time zone of a place in android?

I have a problem in timezone showing. I need to show the time zone and time like "12/11/2014 11:45 IST". I can show the time. But I can't show the zone which place is PST, EST, or IST. How can I do it? Anyone can help me?

My source code is blelow.

    Calendar c = Calendar.getInstance();
    year = c.get(Calendar.YEAR);
    month = c.get(Calendar.MONTH);
    day = c.get(Calendar.DAY_OF_MONTH);
    hour = c.get(Calendar.HOUR_OF_DAY);
    minute = c.get(Calendar.MINUTE);

Here is an example of how you can determine that your application's time is in a different time zone than the system time zone. If yes - open the time settings

TimeZone.setDefault(null) // clear cached timezone
val localeCountry = Locale.getDefault().country // get default country 
code
val availableTimeZoneList = TimeZone.getAvailableIDs(localeCountry).toList() // available time zone list for default country code
val currentTimeZone = TimeZone.getDefault()

if(!availableTimeZoneList.contains(currentTimeZone.id) && availableTimeZoneList.all { TimeZone.getTimeZone(it).rawOffset != currentTimeZone.rawOffset }) {
    startActivity(Intent(android.provider.Settings.ACTION_DATE_SETTINGS))
}

 public static String TimezoneUrl = "https://maps.googleapis.com/maps/api/timezone/json?";

 API_KEY="Your API service key";
 newurl = TimezoneUrl+"location="+myLatitude+","
 +myLongitude+"&timestamp="+System.currentTimeMillis() / 1000 + "&key=" + API_KEY;
 response = makeServiceCall(url, ServiceHandler.GET);

 jsonResponse = new JSONObject(response);
 timesone = jsonResponse.getString("timeZoneName");


 for (int i = 0; i < timesone.length(); i++) {
        if (Character.isUpperCase(timesone.charAt(i))) {
            char c = timesone.charAt(i);
            timezone = timezone + c;
    }
 }

  public String makeServiceCall(String url, int method) {
    return this.makeServiceCall(url, method, null);
 }


 public String makeServiceCall(String url, int method,
    List<NameValuePair> params) {
 try {
    // http client
    DefaultHttpClient httpClient = new DefaultHttpClient();

    //httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "Custom user agent");
    HttpEntity httpEntity = null;
    HttpResponse httpResponse = null;

    // Checking http request method type
     if (method == GET) {
        // appending params to url
        if (params != null) {
            String paramString = URLEncodedUtils    .format(params, "utf-8");
            url += "?" + paramString;
        }
        HttpGet httpGet = new HttpGet(url);

        httpResponse = httpClient.execute(httpGet);

    }
    httpEntity = httpResponse.getEntity();
    response = EntityUtils.toString(httpEntity);

} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

return response;

}

Result will give you IST as you expect Timezone.

You can use SimpleDateFormat to format your Date with TimeZone in simple way. As example, to show date with TimeZone as 12/11/2014 11:45 IST, you can use dd/MM/yyyy HH:mm z format as below where z will represent the TimeZone as like EST, IST.

Calendar cal = Calendar.getInstance();
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm z");
String formatedDate = dateFormat.format(cal.getTime());

Have you use TimeZone.getDefault(): Most applications will use TimeZone.getDefault() which returns a TimeZone based on the time zone where the program is running.

For more info: http://developer.android.com/reference/java/util/TimeZone.html

Try below code also: 

TimeZone tz = TimeZone.getDefault();
System.out.println("TimeZone   "+tz.getDisplayName(false, TimeZone.SHORT)+" Timezon id :: " tz.getID());
