Recently I've had problems with Timezones becaus this year, Daylight Saving Time is extended for 1 week in NSW. The trouble is, there is no world time zone authority, and this has caused some dramas in the applications that I am looking after. The good news is that Sun has released a
Java patch to fix Java's timezone database. For more information, see:
