How to synchronise "absoluteInitialX" for 4 5112's with 2 trigger sources for 2 sets of 5112 (PXI system) ?

The challenge is to get from two 5112 boards a trigger from different signals and measure 3 channels.
Ch0 from the first 5112 witch supplies the trigger via RTSI, and ch0 and ch1 from the second which is on the receiving the RTSI trigger signal.
The same configuration is used for the other two boards.

If I fetch the data, the absoluteInitialX values are not equal, even if i connect the same signals and use the same triggering for the four 5112's.

The difference in absoluteInitialX is approx. 300ms and is not constant and are different after a new initalisation of the boards.

I need this absoluteInitialX to keep track of the relation between the two processes and the relation between triggers over time.

How to sync these absoluteInitialX ?
