Java Date Time display timezone offset

When we talk about Time without timezone's it makes no sense, "Time is relative" so its very important to know either the timezone or the offset of time from GMT in order to understand which part of the world the time belongs to. If you want to display time as offset in Java programming you need to make use of the Date object and the DateFormat object, let us see how this can be achieved,

Code Example: Java Date with GMT Offset:

    public static void main(String[] args) {
        Date myDate = new Date();
        DateFormat dateFormatWithOffset = new SimpleDateFormat("dd-MM-yyyy HH:mm Z");
        System.out.println("Current Time with Offset: " + dateFormatWithOffset.format(myDate));

    }

Output: Current Time with Offset: 26-03-2021 10:00 -0500

As you can see in the above example, we created a Java date object using java.util.Date package, and DateFormat object using java.text.SimpleDateFormat package. Note that Z in the SimpleDateFormat string displays the timezone - the offset in ISO 8601 time zone format. -0500 is the offset of timezone America/Chicago
