RAW/JPEG time offset on files

[StevenJS]

Recently vacationed in Greece and set time/date to local Greek time. In reviewing files back home, noticed RAW files 10 hours ahead of JPEG time (correct shooting time).  There is an offset of 10 hours from here to Greece, but why would RAW/JPEG files not have same time?

Does it sound like a time zone offset? Could be raws don't have a time zone setting. It might also depend on your RAW viewer.
