- ‘true’ if this time zone uses daylight saving time
- ‘false’ if this time zone does not use daylight saving time
Below program demonstrates the above-mentioned function:
Example 1:
// Program to demonstrate the // useDaylightTime() import java.util.*; public class GFG { public static void main(String[] args) { // Create TimeZone object TimeZone obj = TimeZone.getTimeZone( "Europe/Rome" ); // Checking day light time // and displaying the result System.out.println( "Day light time is = " + obj.useDaylightTime()); } } |
Day light time is = true
Example 2:
// Program to demonstrate the // useDaylightTime() import java.util.*; public class GFG { public static void main(String[] args) { // Create TimeZone object TimeZone obj = TimeZone.getTimeZone( "Pacific/Pago_Pago" ); // checking day light time // and printing the result System.out.println( "Day light time is = " + obj.useDaylightTime()); } } |
Day light time is = false
