I have the date string "2015-01-12T13:00:00.000+02:00". Looking at the JavaDoc I see the following:
z time-zone name zone-name Pacific Standard Time; PST Z zone-offset offset-Z +0000; -0800; -08:00;
So I would suspect that to parse it I would have to use upper-case 'Z' because I have the Zone format given in +02:00:
DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000Z");
But with that I get a parse error.
If I use lower-case 'z' it works:
DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000z")
Does anyone know what is going on?
CODE:
DateTimeFormatter changetimeParser_Z = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000Z");
DateTimeFormatter changetimeParser_z = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.000z");
String time = "2015-01-12T13:00:00.000+02:00";
ZonedDateTime time1 = ZonedDateTime.parse(time, changetimeParser_z);
System.out.println(time1);
ZonedDateTime time2 = ZonedDateTime.parse(time, changetimeParser_Z);
System.out.println(time2);
Exception stack trace:

I would believe it's an error in the Javadoc and this part is a mistake

Z zone-offset offset-Z +0000; -0800; -08:00;
because if you read further you find the explanation of the offset Z
Offset Z: This formats the offset based on the number of pattern letters. One, two or three letters outputs the hour and minute, without a colon, such as '+0130'. The output will be '+0000' when the offset is zero. Four letters outputs the full form of localized offset, equivalent to four letters of Offset-O. The output will be the corresponding localized offset text if the offset is zero. Five letters outputs the hour, minute, with optional second if non-zero, with colon. It outputs 'Z' if the offset is zero. Six or more letters throws IllegalArgumentException.
Which complies RFC 822.
For me the pattern should behave same as for SimpleDateFormat
