Converting from Milliseconds to UTC Time in Java

Question

I\'m trying to convert a millisecond time (milliseconds since Jan 1 1970) to a time in UTC in Java. I\'ve seen a lot of other questions that utilize SimpleDateFormat to chan

Answer 1

java.time option

You can use the new java.time package built into Java 8 and later.

You can create a ZonedDateTime corresponding to that instant in time in UTC timezone:

ZonedDateTime utc = Instant.ofEpochMilli(1427723278405L).atZone(ZoneOffset.UTC);
System.out.println(utc);

You can also use a DateTimeFormatter if you need a different format, for example:

System.out.println( DateTimeFormatter.ofPattern("EEE MMM dd HH:mm:ss").format(utc));
