Closed 8 days ago.

import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class Main {
    public static void main(String[] args) {
        DateTimeFormatter utcFormatter = DateTimeFormat.forPattern("EEE MMM dd HH:mm:ss zzz yyyy");
        DateTime dateTime1 = utcFormatter.parseDateTime("Thu Mar 28 12:26:50 UTC 2019");

        DateTimeZone istZone = DateTimeZone.forID("Asia/Kolkata");
        DateTimeFormatter istFormatter = utcFormatter.withZone(istZone);
        String dtstrIndiaTimezone = istFormatter.print(dateTime1);
        System.out.println(dtstrIndiaTimezone);

        DateTime dateTime2 = istFormatter.parseDateTime(dtstrIndiaTimezone);// throws exception
        // System.out.println(dateTime2);
    }
}

Executing the code given above shows the date time string in IST but throws the following exception when trying to parse the same:

Thu Mar 28 17:56:50 IST 2019
Exception in thread "main" java.lang.IllegalArgumentException: Invalid format: "Thu Mar 28 17:56:50 IST 2019" is malformed at "IST 2019"
    at org.joda.time.format.DateTimeFormatter.parseDateTime(DateTimeFormatter.java:945)
    at Main.main(Main.java:16)

How to do it? Is it a bug in the API?

Note: I know how to do it using java.time classes.

回答1:

I am sorry, you can’t. The documentation says:

Zone names: Time zone names ('z') cannot be parsed.

From the documentation of DateTimeFormat
