How does Java 8 handle Daylight Saving Time?

How does Java 8 handle Daylight Saving Time?

Java 8 introduced the Date-Time API, which provides better handling of time zones and Daylight Saving Time (DST). It uses the java.time package, which includes classes like ZonedDateTime and ZoneId.

Can you give me an example of how to use ZonedDateTime with DST?

Sure! You can create a ZonedDateTime instance like this:

ZonedDateTime zdt = ZonedDateTime.now(ZoneId.of("America/New_York"));

This will automatically adjust for DST based on the current date.

What happens if I try to create a date during the DST transition?

If you create a date during the transition, Java will handle it correctly. For example, if you try to create a time that doesn't exist due to the spring forward, it will throw an exception.

Is there a way to check if a date is in DST?

Yes! You can use the getOffset() method on a ZonedDateTime instance to check if the offset is different from the standard time offset.
