How about meassuring it directly? For starters, take a look at zttest.c .
(Though it could use some slightly better accuracy).
Not sure how accurate is zttest.c.
Will run some test to see it's accuracy.

Anybody sucessfully got stable 1000Hz clock without Digium harware and kernel
2.6?
We need to consult some peoples how to clock asterisk stable with exactly 1000
Hz without much kernel/drives patching/tweaking.
Some test results we made so far:
2.6 with digium card - stable 1000 Hz.
2.6 with

How are you doing this? I saw a couple developers talk
about rewriting ztdummy yo use the new hi-res kernel timers
(kernel2.6.17), but did
