java version "1.3.0rc1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0rc1-T)
Java HotSpot(TM) Client VM (build 1.3.0rc1-S, mixed mode)

getTime() for a JarEntry returns the wrong time. Try the following simple
application in JDK 1.2.2 and JDK 1.3RC1, you'll get an incorrect time, ie date,
from the 1.3 VM. Run the enclosed, click the button, select a jar file, and
then look at the output in sysout. I have looked into this and it is the
getTime that is returning a different value - it is not the date class.
