The specs also state that the DCO could be between 25Khz and 41KHz (32.7KHz typ), but once trimmed, will remain +/- 0.5% from 0 to 70 degrees C. I consider that quite stable for no crystal.
Would the accuracy be the same for RTI oscilator?
Has anyone used this MCU's internal clock source for real time clock purposes?
The accuracy of this clock is quoted as +/- 30% so I couldn't imagine its stability would be too brilliant.

Yep Peg,
I would see a typical 25% for this kind of really simple RC-oscillators.
The 30% is probably quoted with some guard band to guarantee it across production.
