Daylight Saving Time Changes in 2007 for USA

Can anyone give me solution how to handle Daylight saving Time changes in 2007 in USA for JDK 1.3.x releases? We are using this due to some vendor dependency. We can抰 upgrade to higher versions up to middle of the 2007. I would be thankful if somebody gets back to me.

Use J2SE 1.3.1_18 or later in 2007. See also http://java.sun.com/developer/technicalArticles/Intl/USDST/

I have a similar issue where we cannot upgrade the jdk 1.1 without involving a lot of effort. If we keep the same old jdk, can someone tell me if use of Date and Calendar api will be impacted by the Daylight saving change.....provided the timezone is default and not explicitly set to EST. Also there isnt any timezone related buss logic.
