Get Date & Time From Internet

In this tutorial, I will tell you how to get date and time from internet.

build.gradle(module:app)

                            implementation 'org.jsoup:jsoup:1.13.1'
                        

Now add Internet permission in file
AndroidManifest.XML

                            <uses-permission android:name="android.permission.INTERNET"/>
                        

Create new Java class named

TimeClass.java

                        import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;

import java.io.IOException;
import java.net.URL;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;

public class TimeClass {

    public static final String URL = "https://time.is/Unix_time_now/";
    public static final String TIME_PATTERN = "dd/MM/yyyy hh:mm a";

    public String getTimeMillis() throws IOException {

        Document document = Jsoup.parse(new URL(URL).openStream(), "UTF-8", URL);

        String[] tags = new String[]{
                "div[id=time_section]",
                "div[id=clock0_bg]"
        };

        Elements elements = document.select(tags[0]);

        for (String tag : tags) {
            elements = elements.select(tag);
        }
        return elements.text() + "111";
    }

    public String toReadableTime(long timeMillis) {
        Calendar cal = Calendar.getInstance();
        cal.setTimeInMillis(timeMillis);
        SimpleDateFormat dateFormat = new SimpleDateFormat(TIME_PATTERN, Locale.ENGLISH);

        return dateFormat.format(cal.getTime());
    }

    public Date toDate(String timeString) throws ParseException {
        SimpleDateFormat dateFormat = new SimpleDateFormat(TIME_PATTERN, Locale.ENGLISH);

        return dateFormat.parse(timeString);
    }

}
