Convert iso8601 string date time format to date in Java

Question

All,

I know I have asked a similar question on parsing an ISO8601 date string into a Date using Java before, but this is a more specific problem using the SimpleDateFormat class.

I have read the article Wiki ISO8601 Date.

I have been supplied an XML file from a customer which has a date and time with the following format:

2012-08-24T12:15:00+02:00

According to the Wiki article this is valid which is fair enough.

Given the following code to parse this string, a ParseException is thrown with the message "Unparseable date: "2012-08-24T12:15:00+02:00"".

String inputDate = "2012-08-24T12:15:00+02:00";
String format = "yyyy-MM-dd'T'HH:mm:ssz";

SimpleDateFormat sdf = new SimpleDateFormat(format);
Date d = sdf.parse(inputDate);

The problem is with the colon in the timezone specifier. +02:00 in the timezone causes the exception to be thrown. +0200 works fine.

Question is, is it possible to parse this type of string with the SimpleDateFormat?

Thanks

Andez

No, using SimpleDateFormat, parsing this date is not possible (at least not in jdk 6 or lower). We had to write our own adapter for this ourselves.

Note, since this format is a valid part of XML Schema, you can use the DatatypeConverter.parseDateTime() method to parse this date.

+1 Better than using SimpleDateFormat – Damo Mar 13 '13 at 05:52
This is throwing an IllegalArgumentException for me when I try to parse "2015-10-19T18:58:23.000+0000" – Kimball Robinson Oct 22 '15 at 17:00
@KimballRobinson - probably because that does not fit the xsd dateTime format (you are missing the ':' in the timezone offset). – jtahlborn Oct 22 '15 at 17:49
@jtahlborn, I'm getting time stamps from the Salesforce REST api, so I don't control the format. I am using Joda Time's library to parse the timestamps now. – Kimball Robinson Oct 23 '15 at 13:44

The best answer I have found is on this question.

Converting ISO 8601-compliant String to java.util.Date

Quote: The easier solution is possibly to use the data type converter in JAXB, since JAXB must be able to parse ISO8601 date string according to the XML Schema specification. javax.xml.bind.DatatypeConverter.parseDateTime("2010-01-01T12:00:00Z") will give you a Calendar object and you can simply use getTime() on it, if you need a Date object.
