clock accuracy cfp ctr-500

I have an application using a cFP CTR-500 counter module in a ethernet backplane

I have set up 4 counters cascade coupled - so they act as a 64 bit counter. They are gated by a switch (actually only the first counter is gated - the other counters has the count source set to 'previous channel'). On the first counter, the count input is set to '32khz reference'.

 

Basically i'm measuring the time the switch is activated.

 

I want to calculate the accuracy of this time measuremt - but hours of searching gave no indication of the accuracy of this clock. I'm looking for short- and long term stabiliy, temperature influence and likes. Where can this be found? what can I expect from this measurement??

 

Best Regards
