The java.util.GregorianCalendar.getTimeZone() method is an in-built method in Java which fetches the time zone and returns the TimeZone object associated with this calendar.
Syntax:
public TimeZone getTimeZone()
Parameters: This method does not accept any parameter.
Return Values: This method returns a TimeZone object which denotes the time zone of this calendar.
Examples:
Input : Mon Jul 23 19:45:33 UTC 2018
Output : Coordinated Universal Time
Input : Wed Oct 23 20:02:52 UTC 2019
cal.setTimeZone(TimeZone.getTimeZone("CST"));
Output : Central Standard Time
Below programs illustrate the java.util.GregorianCalendar.getTimeZone() function in Java:
Program 1:
Java
// Java Program to illustrate// GregorianCalendar.getTimeZone()// functionimport java.io.*;import java.util.*;class GFG { public static void main(String[] args) { // Create a new calendar GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); //Display the current date and time System.out.println("Current Date and Time : " + cal.getTime()); /* Creating a Time Zone object and storing this TimeZone */ TimeZone t = cal.getTimeZone(); // Display the time zone System.out.println("Time Zone : " + t.getDisplayName()); }} |
Output:
Current Date and Time : Wed Jul 25 11:25:16 UTC 2018 Time Zone : Coordinated Universal Time
Program 2: In this program, we use setTimeZone() to change the current time zone and then fetch the new time zone using getTimeZone() method.
Java
// Java Program to illustrate// GregorianCalendar.getTimeZone()// functionimport java.io.*;import java.util.*;class GFG { public static void main(String[] args) { // Create a new calendar GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance(); // Display the current date and time System.out.println("Current Date and Time : " + cal.getTime()); // Changing the current time zone cal.setTimeZone(TimeZone.getTimeZone("CST")); /* Creating a Time Zone object and storing the TimeZone */ TimeZone t = cal.getTimeZone(); // Display the time zone System.out.println("Time Zone : " + t.getDisplayName()); }} |
Output:
Current Date and Time : Wed Jul 25 11:25:22 UTC 2018 Time Zone : Central Standard Time
