Yaron Gvili updated ARROW-18427:
--------------------------------
Description: Currently, `AsofJoinNode` supports a tolerance that is
non-negative, allowing past-joining, i.e., joining right-table rows with a
timestamp at or before that of the left-table row. This issue will add support
for a negative tolerance, which would allow future-joining too. (was:
