This is a terrible solution if you need to work with more than just UTC (aka GMT) and one other time zone. For example, if you need to present datetimes to users in a web app and the users may be in any time zone, then Date::Calc will be very painful to use. This was one of the motivations for writing DateTime. -dave /*======================= House Absolute Consulting www.houseabsolute.com =======================*/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
