Hi Nic,
I don't think the returned date as such is incorrect. The problem occurs
when you represent the date as a string. What timezone do you use when
you do that? Do you simply use d.toString() ? If so, the default
timezone for your JVM is incorrect and that's the source of the problem.
Regards,
Thomas Hallgren
