LocationManager locMan = (LocationManager) arg0.getSystemService(Context.LOCATION_SERVICE);
long networkTS = locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER).getTime();
Toast.makeText(arg0,""+networkTS,Toast.LENGTH_LONG ).show();
Date date = new Date(networkTS);
SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
format.setTimeZone(TimeZone.getTimeZone("GMT+5:30"));
String formatted = format.format(date);
Toast.makeText(arg0,""+formatted,Toast.LENGTH_LONG ).show();
