JSON日期到Java日期

I could not find this anywhere. I fetch some JSON from an API that returns standard JSON dates. You can see the format by running this code in a JavaScript console:

> new Date().toJSON();
"2010-10-27T11:58:22.973Z"

Well, actually, the API I'm working with is not returning the millisecond part, and sometimes it returns a timezone instead of Z, so dates can look like any one of these:

• 2010-10-27T11:58:22Z
• 2010-10-27T11:58:22+03:00

Parsing these kinds of dates is somewhat cumbersome. Is there any way to parse these kinds of dates, using org.json?

我目前的解决方案是:

public static Date parseDateTime(String dateString) {
    if (dateString == null) return null;
    DateFormat fmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ssZ");
    if (dateString.contains("T")) dateString = dateString.replace('T', ' ');
    if (dateString.contains("Z")) dateString = dateString.replace("Z", "+0000");
    else
        dateString = dateString.substring(0, dateString.lastIndexOf(':')) + dateString.substring(dateString.lastIndexOf(':')+1);
    try {
        return fmt.parse(dateString);
    }
    catch (ParseException e) {
        Log.e(Const.TAG, "Could not parse datetime: " + dateString);
        return null;
    }
}

啊！
