SimpleDateFormat(“Z”) in Java

The Z means "zero hour offset", also known as "Zulu time" (UTC) in the ISO 8601 time representation. However, ACP 121 standard defines the list of military time zones and derives the "Zulu time" from the Greenwich Mean Time (GMT).

TimeZone can be formatted in z, Z or zzzz formats.

The following is an example that displays how to implement SimpleDateFormat(“Z”) −

Example

 Live Demo

import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Calendar;
public class Demo {
   public static void main(String[] args) throws Exception {
      // displaying current date and time
      Calendar cal = Calendar.getInstance();
      SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s zzzz");
      System.out.println("Today's date = "+simpleformat.format(cal.getTime()));
      // displaying hour
      Format f = new SimpleDateFormat("H");
      String strHour = f.format(new Date());
      System.out.println("Current Hour = "+strHour);
      // displaying minutes
      f = new SimpleDateFormat("mm");
      String strMinute = f.format(new Date());
      System.out.println("Current Minutes = "+strMinute);
      // displaying seconds in two-digits
      f = new SimpleDateFormat("ss");
      String strSeconds = f.format(new Date());
      System.out.println("Current Seconds = "+strSeconds);
      f = new SimpleDateFormat("a");
      String strMarker = f.format(new Date());
      System.out.println("Current AM/PM Marker = "+strMarker);
      f = new SimpleDateFormat("Z");
      String strOffset = f.format(new Date());
      System.out.println("Offset = "+strOffset);
   }
}

Output

Today's date = 26/November/2018 08:18:9 Coordinated Universal Time
Current Hour = 8
Current Minutes = 18
Current Seconds = 09
Current AM/PM Marker = AM
Offset = +0000
