> The boundaries of LESS_THAN and GREATER_THAN predicates are not correctly computed if
the time attribute of the right table is referenced on the left side of the join predicate.
> Instead of adding (subtracting) 1 millisecond, 1 millisecond is subtracted (added). 
> Hence, the boundary is off-by-2.
