How do I get a colon in timezone of Joda DateTime?

Question

I'm trying to parse my DateTime in a specific format to String . Code:

DateTimeFormatter fmt = DateTimeFormat.forPattern("yyy-MM-dd'T'HH:mm:ss").withOffsetParsed();
DateTime formattedDate = fmt.parseDateTime(asString($client/date));
String result = formattedDate.toString("yyyy-MM-ddZ");

Result:

2018-01-15+0100

What I want:

2018-01-15+01:00

Answer 1

You should read the docs .

Zone: 'Z' outputs offset without a colon, 'ZZ' outputs the offset with a colon, 'ZZZ' or more outputs the zone id.

so your code should be:

DateTimeFormatter fmt = DateTimeFormat.forPattern("yyy-MM-dd'T'HH:mm:ss").withOffsetParsed();
Date formattedDate = fmt.parseDateTime(asString($client/date));
String result = formattedDate.toString("yyyy-MM-ddZZ");

Answer 2

You need to use ZZ to output with a colon. So:

String result = formattedDate.toString("yyyy-MM-ddZZ");

will output:

2018-01-15+01:00
