You are correct - when I load the linux serialized file, I get the following on my BSD box: [veldy@fuggle veldy]$ java DateTest r test.out Restored: Tue May 07 23:00:00 GMT-06:00 3901 That is one hour back - but it looks to me that the Linux JDK is inappropriately reading the timezone information as CDT and that FreeBSD is correctly reading it. Thus the Linux JDK serialized incorrectly.
