Joda Time - different between timezones

Question

I want to convert the current time to the time in a specific timezone with Joda time.

Is there a way to convert DateTime time = new DateTime() to a specific timezone, or perhaps to get the number of hours difference between time.getZone() and another DateTimeZone to then do time.minusHours or time.plusHours?

It's not really clear whether you've already got the current time or not. If you've already got it, you can use withZone:

DateTime zoned = original.withZone(zone);

If you're just fetching the current time, use the appropriate constructor:

DateTime zoned = new DateTime(zone);

or use DateTime.now:

DateTime zoned = DateTime.now(zone);

check out DateTimeZone & Interval at
http://joda-time.sourceforge.net/apidocs/org/joda/time/DateTimeZone.html & http://joda-time.sourceforge.net/apidocs/org/joda/time/Interval.html

DateTime dt = new DateTime();
    // translate to London local time
    DateTime dtLondon = dt.withZone(DateTimeZone.forID("Europe/London"));

Interval:

Interval interval = new Interval(start, end); //start and end are two DateTimes
