The getOffset(int era, int yr, int mon, int day, int dayOfWeek, int millisec) method of TimeZone class in Java is used to know the offset value of this TimeZone at a specific date or modified date in case of daylight savings, from the UTC or the Universal Time Coordinated. This offset value can be added to get the local time. Syntax:
public abstract int 
    getOffset(int era, int yr, 
              int mon, int day, 
              int dayOfWeek, int millisec)
Parameters: The method can take the below mentioned parameters.
  • era: This is of integer type and refers to the era of the given date.
  • yr: This is of integer type and refers to the year in the given date.
  • month: This is of integer type and refers to the month in the given date.
  • day: This is of integer type and refers to the day-in-month of the given date.
  • dayOfWeek: This is of integer type and refers to the day-of-week of the given date.
  • milliseconds: This is of integer type and refers to the milliseconds in day in standard local time.
Return Value: The method returns the offset value in milliseconds that can be added to GMT to get local time. Below programs illustrate the working of getOffset() Method of TimeZone: Example 1:
// Java code to illustrate getOffset() method
  
import java.util.*;
  
public class TimeZoneDemo {
    public static void main(String args[])
    {
  
        // Creating a TimeZone
        TimeZone offtime_zone
            = TimeZone.getTimeZone("Europe/Rome");
  
        // Checking the offset for the systems date
        System.out.println("The Offset Value is:"
                           + offtime_zone.getOffset(
                                 1, 2018, 5, 12, 2, 500));
    }
}

                    
Output:
The Offset Value is:7200000
Example 2:
// Java code to illustrate getOffset() method
  
import java.util.*;
  
public class TimeZoneDemo {
    public static void main(String args[])
    {
  
        // Creating a TimeZone
        TimeZone offtime_zone
            = TimeZone.getTimeZone("Pacific/Pago_Pago");
  
        // Checking the offset for the systems date
        System.out.println("The Offset Value is:"
                           + offtime_zone.getOffset(
                                 1, 1995, 9, 20, 2, 700));
    }
}

                    
Output:
The Offset Value is:-39600000
