How do I handle time zone differences in Java?

How do I handle time zone differences in Java?

You can use the java.time package, specifically the ZonedDateTime and ZoneId classes, to manage time zones.

Can you show me an example of converting a time from one zone to another?

Sure! Here's a simple example:

ZonedDateTime dateTimeInNewYork = ZonedDateTime.now(ZoneId.of("America/New_York"));
ZonedDateTime dateTimeInLondon = dateTimeInNewYork.withZoneSameInstant(ZoneId.of("Europe/London"));
System.out.println(dateTimeInLondon);

What if I need to handle daylight saving time?

The ZonedDateTime class automatically adjusts for daylight saving time based on the time zone rules.

Are there any libraries that can help with time zone conversions?

Yes, libraries like Joda-Time can also help, but the java.time package is recommended for modern Java applications.
