ZonedDateTime documentation seems to be incorrect

[AceHack]

It says:
https://github.com/FasterXML/jackson-modules-java8/tree/master/datetime

For string representation default formats for deserialization are:

Java type	Format
ZonedDateTime	DateTimeFormatter.ISO_ZONED_DATE_TIME

But in the code I see:

jackson-modules-java8/datetime/src/main/java/com/fasterxml/jackson/datatype/jsr310/ser/ZonedDateTimeSerializer.java

Lines 22 to 23 in 1534c55

	// ISO_ZONED_DATE_TIME is not the ISO format, it is an extension of it
	this(DateTimeFormatter.ISO_OFFSET_DATE_TIME);

Yes, and the comment could be improved too. A little ambiguous though perhaps trying to explain why ISO_OFFSET_DATE_TIME is used and not ISO_ZONED_DATE_TIME.

@cowtowncoder please confirm
As per the issue description documentation seems to be incorrect. Is that correct? or implementation needs to be updated to match the documentation?

[cowtowncoder]

@mydata Generally documentation should match implementation unless indicated otherwise. So I'd start with that.

@cowtowncoder @pjfanning as far as I can see the documentation was fixed a long time ago with 92c9e0d and the code was also modified to include a more extensive comment why ISO_OFFSET_DATE_TIME is used. IMHO this ticket can be closed.
