I'm not sure there is anything else we can do to help you - the only other alternative would be to use the FPGA board to monitor this trigger line, and when it sees a trigger fires an IRQ to the host program which is waiting on this - and then at this point get the current time in software.
I'm not sure that there is a more accurate way of getting this timing information, as it seems its just a limitation of this LIN card that you have.
