Re: NodeType.setProperty behaviour

I just noted that I missed that you actually posted your code in the
first mail, and you also use the joda DateTime API. Then my comments
were a bit off ;-) See below for some more notes.

There is no "UTC" timezone ID in java, you should try "Etc/UTC"

Also Calendar.getInstance() is very dangerous, as it uses the default
timezone of the current JVM (mostly not what you want)

Try this:

public Calendar getUTCDate(Calendar in) {
    Calendar out = Calendar.getInstance(TimeZone.getTimeZone("Etc/UTC"));
    out.setTimeInMillis(in.getTimeInMillis());
    return out;
}

then use it like this (assuming the story.getStartDate() already has
the proper user timezone):

storyNode.setProperty("startDate", getUTCDate(story.getStartDate()));

(there is a setProperty() method that accepts a Calendar as value and
saves it right as jcr DATE property).

Yes, one has to know which combinations are safe ;-) The order of
calling methods is sometimes important, as not always the internal
time will be recalculated...
