Getting the current Datetime in a country without using system time

I´m trying to get the real current in my country, however the methods I used are dependant on the time on my device. I set the time on my device to 9 AM while in reality it was 7 PM and the following method returned 8 AM, which is ofcourse incorrect.

simpledate.setTimeZone(TimeZone.getTimeZone("Europe/Slovakia"));
to_time = simpledate.format(new Date());

Is there any way to get the real time in the country without it being dependant on system time? I assume the device must be connected to the Internet. Also my country uses DST, so it must take that into consideration too. Browsed similar question, none helped.

package com.myapp.utils;

import android.os.StrictMode;
import java.io.IOException;
import org.apache.commons.net.time.TimeTCPClient;


public class InternetTime {

    public static long getFechaHora() {
        long time = 0;
        try {
            TimeTCPClient client = new TimeTCPClient();

            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
            StrictMode.setThreadPolicy(policy);

            try {
                client.setDefaultTimeout(5000);
                client.connect("time.nist.gov");
                //System.out.println(client.getDate());
                time = client.getTime();
            } finally {
                client.disconnect();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return time;
    }

}

There are two ways to do that whether you will need to have access to a webservice that provides current date and time in JSON format or XML, OR, you could parse the time from a website, like

http://www.timeanddate.com/worldclock/

Another alternative code snippet for getting time from a Time Server. You need an Apache Commons Net libray for this to work. 

import org.apache.commons.net.time.TimeTCPClient;

public final class GetTime {

public static final void main(String[] args) {
    try {
        TimeTCPClient client = new TimeTCPClient();
        try {
            client.setDefaultTimeout(60000);
            client.connect("time.nist.gov");
            System.out.println(client.getDate());
        }
        catch (IOException e) {
           e.printStackTrace();
        }
        finally {
           client.disconnect();
        }
    }
}

You can find other time servers at HERE. Just replace time.nist.gov with one.
