How can I intersect two time array?

I have two time array (at a resolution of 1 second), each of which with gaps at different time. The start and end time is equal for the two array. The dimension is different, that is the number of points for each array is different. I would like to check point to point from each array to verify equality, within 10-9 precision. I could use intersect, ma several point are different at 10 decimal point, so intersect understand them as different. Can I use a function to bypass this issue? Or there is other procedures to obtain a third time array and respective index? Thank you very much
