REST API task query due date dueAfter dueBefore error

[ssun]

{
errorMessage: "The given value for query-parameter 'dueAfter' is not a valid date: 2014-05-23T02:40:53",
statusCode: 400
}

What I passed is an ISO date according to http://activiti.org/userguide/#restTasksGet.
Both encoded or not fails
http://localhost:8080/activiti-rest/service/runtime/tasks?assignee=delmstrom&name=mustShip&dueAfter=...
http://localhost:8080/activiti-rest/service/runtime/tasks?dueAfter=2014-05-23T02%3A40%3A53

Any help is appreciated!

Thank you in advance!

In our unit tests, we use the following code

protected String getISODateString(Date time) {
    return ISO8601Utils.format(time, true);
  }

This generates a date like this: '2014-05-27T08:25:11.670Z'. Notice the Z at the end (timezone?)

Thank you jbarrez. If the 'dueOn' did not work, I would have guessed that there is something wrong with my date format. I wish the guide can be more clear.
