java SimpleDateFormat

You can try

String format = "yyyy-MM-dd'T'HH:mm:ssz";

Reference : from Javadoc

Text can be quoted using single quotes (') to avoid interpretation.

The time you're trying to parse appears to be in ISO 8601 format. SimpleDateFormat unfortunately doesn't support all the same timezone specifiers as ISO 8601. If you want to be able to properly handle all the forms specified in the ISO, the best thing to do is use Joda time.

This example is straight out of the user guide:

DateTime dt = new DateTime("2004-12-13T21:39:45.618-08:00");
