System time drifting

I have just noticed that the system date/time drifts badly.

-2.5% to be precise. The rtc time (running from the 24MHz crystal) is good, but the system time running internally runs slow.

Losing 15 seconds every 10 minutes is not good when you are dispalying a clock to the user! I have just checked it on the EVK and it does the same.

Has anyone else noticed this? And/or found a fix for it?
