Variation of  RTI interrupt time due variation in clk source ?  S08AW32

From Data sheet of AW32 i see that Real Time Intr clock source (1kHz) can have a deviation of 30%in period from 700us to 1300us, while desired is 1000us.

I have selected the duration of interrupt to be 8ms.

So I would like to know the relation of clock source and the intr occurance period(ideal 8ms) and hence the change in intr occurance period due to change in clk source.

Any equations relating the clk src and intr occurance period ?

Added p/n to subject.
