'Java ParseException Unparseable date when date string is UTC+13:00 timezone

I am getting weird error which I can't get around easily. This is my code

DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.[S][SS][SSS][SSSS][SSSSS][SSSSSS][SSSSSSS][SSSSSSSS][SSSSSSSSS]X");
df.setTimeZone(TimeZone.getDefault());
Date issued = df.parse(this.dateAndTimeOfIssue);

I am getting exception java.text.ParseException: Unparseable date: "2018-02-13T00:00:51.045+13:00"

Does anyone knows what is causing error?

java

tl;dr

Date.from( 
    OffsetDateTime
    .parse( "2018-02-13T00:00:51.045+13:00" )
    .toInstant() 
)

Details

You are using terrible date-time classes that were years ago supplanted by the modern java.time classes defined in JSR 310. Avoid Date/Calendar.

For a date with time of day as seen with a particular offset, use OffsetDateTime class.

Your input text complies with the standard ISO 8601 format used by default in the java.time classes. So no need to specify a formatting pattern.

OffsetDateTime.parse( "2018-02-13T00:00:51.045+13:00" )

If you must use the legacy classes to interoperate with old code not yet updated for java.time, you can convert to and fro. Use the new conversion methods added to the old classes.

java.util.Date d = Date.from( myOffsetDateTime.toInstant() ) ;

Your issue is that SimpleDateFormat does not support the optional sections - that is, the enclosure of parts of the format in [ ] characters. You need to either

  • abandon the use of the optional sections,
  • write your own DateFormat implementation,
  • switch to the more modern classes in the java.time package.

The third option is usually the best - the java.time package has been around for many years now, and the DateTimeFormatter class does indeed support the [ ] notation. But if you have to deal with legacy date and time classes, you might be best to write your own DateFormat.
