I've just noticed that my Finder preview dates are all wrong.
In column view, when an item is highlighted, the Created/Modified dates are all about 34 years in the future.

This is on a two-week old G4 iBook (10.3.5), and only applies to files & folders which were transfered over when I traded the old iBook in. Anything I have created since then has the correct time & date. If I modify one of these old documents, the Created date stays in the future, and the Modified date becomes correct.
Has this happened to anyone else, & is there a quick fix for it?
Thanks.
