Forgive me if this is a daft question... but where does the DFP get it's time reference from?

If I enable the clock, which I'd like too.. it bares no relation to the time of the PC that Cortex is running on, or the clock that's displayed in the top right hand corner of Cortex itself, it's about 1 minute fast.

I'd like to display the clock..but it's wrong!

Er... Help?

Chris.
