This has happened to me also. I've had this dapper system installed for several weeks now, and it is up-to-date. I had not rebooted for several days, but yesterday I did so and this behaviour began.
Changing time/date via the applet is not permanent, as it reverts to GMT at reboot. The system acknowledges the correct timezone (for me, Australia/Sydney), however it seems that data for said timezone has been wrongly changed or corrupted. Sychronising with the internet server does not do anything to help.
