What is time zones and DST in Java?

Time zones in Java represent the geographical regions where the same standard time is used. They account for local time differences across various regions globally. The Java programming language provides robust support for time zone handling, primarily through the `java.time` package which was introduced in Java 8.

Daylight Saving Time (DST) is a practice of moving the clock forward by one hour during the warmer months to extend evening daylight. Java's time zone support takes DST into account, adjusting times automatically as needed based on the specific rules of each time zone.

Here is an example of how to work with time zones and DST in Java:

import java.time.ZonedDateTime; import java.time.ZoneId; public class TimeZoneExample { public static void main(String[] args) { // Get current date and time in the system default time zone ZonedDateTime currentDateTime = ZonedDateTime.now(); System.out.println("Current date and time: " + currentDateTime); // Get date and time in a specific time zone ZonedDateTime specificZoneDateTime = ZonedDateTime.now(ZoneId.of("America/New_York")); System.out.println("New York time: " + specificZoneDateTime); } }
