How do I handle time zones in Java?

How do I handle time zones in Java?

In Java, you can use the java.time package, specifically the ZonedDateTime class, to handle time zones.

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

Sure! You can use ZonedDateTime to convert time. Here's a quick example:

ZonedDateTime now = ZonedDateTime.now(ZoneId.of("America/New_York"));
ZonedDateTime tokyoTime = now.withZoneSameInstant(ZoneId.of("Asia/Tokyo"));
System.out.println(tokyoTime);

What if I want to get the current time in UTC?

You can get the current time in UTC using ZonedDateTime.now(ZoneOffset.UTC). Here's how:

ZonedDateTime utcNow = ZonedDateTime.now(ZoneOffset.UTC);
System.out.println(utcNow);

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

Yes, libraries like Joda-Time can help, but since Java 8, the built-in java.time package is recommended for time zone handling.
