Hi Paul,
Sorry, but, nothing wrong to me here:
DateTime now = new DateTime(2007, 10, 28, 01, 20, 0, 0,
DateTimeZone.forID("Europe/Dublin") );
out.println(now + " " + now.getZone()); //2007-10-28T01:20:00.000Z Europe/Dublin
now = now.plusHours(1);
out.println(now + " " + now.getZone()); //2007-10-28T02:20:00.000Z Europe/Dublin
1) What's the VM default timezone? GMT? If yes, you can change it to
Europe/Dublin using System.setProperty?
2) Do you update the TZ information in Joda-time jar file, to
recognize the summer time in Europe/Dublin? (I don't know if your ST
is fixed or not) Instructions you find in
http://joda-time.sourceforge.net/tz_update.html
3) Do you see the problem with now.plusHours(1) when you insert this
time in an database? If yes, remember: the DateTime class is
immutable; when you call new DateTime with parameters, only the fiels
are updated (year, month, day, hour, minute, second). The
getTimeInMillis is not updated. Use MutableDateTime instead.
