I originally posted this with on X-E1 forum, and everyone thought it wasn't really a problem. I can't find the poast now.
I had thought it was a Sandisk problem, but last week a tried a Fuji [badged?] 64GM SD and had the same problem -- basically the file shows 7 hours too early. The Exif is correct.
I still don't believe this is a problem that isn't easy to firmware fix. Especially now that we are entering the 512 MB era.
