Unparseable Date Error when parsing UTC string through SimpleDateFormat to Date

问题

I'm trying to write something that will take in a string with the below format in UTC time and format it to the local time zone grabbed from the phone. However, despite looking at SimpleDateFormat documentation, I'm running across the error that my sample string is unparseable:

W/System.err﹕ java.text.ParseException: Unparseable date: "2014-07-16T21:00:00:000+0000" (at offset 19)
W/System.err﹕ at java.text.DateFormat.parse(DateFormat.java:555)
[...]
D/Set time:﹕ Wed Jul 16 15:10:03 PDT 2014
D/TimeInMilli:﹕ 1405548603565

Code:

Calendar cal = Calendar.getInstance();
TimeZone tz = cal.getTimeZone(); //Get phone's PST zone

String UTCinput = "2014-07-16T21:00:00:000+0000"; //2:00PM PST
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
format.setTimeZone(tz);

Date dateCal = new Date();

try {
    dateCal = format.parse(UTCinput);
} catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

cal.setTime(dateCal);
Log.d("Set time: ", String.valueOf(dateCal));
Log.d("TimeInMilli: ", String.valueOf(cal.getTimeInMillis()));

What is the issue with the way I'm parsing?

回答1:

Your input String needs to match your DateFormat pattern

String UTCinput = "2014-07-16T21:00:00.000+0000"; //2:00PM PST
                                      ^--- was ":"
