I know this is an old post, but I'm having exactly the same problem with exactly the same model & wonder if anyone found a resolution. I am able to correctly set the time using 'copy your computer's time and settings', but after a day or so it resets itself to 01/02/2000.
I have tried setting an ntp server but it does not change the time, even after several restarts (BTW, fr.pool.ntp.org doesn't work also because the system looks for an ip address, not a URL).
