      The forum sync function (determine last post) is using the post_id to determine the "last post" of the forum. This does not always generate the correct result, depending on the state of the database - specifically, when a bulletin board is imported from elsewhere into phpBB.

      Using the post_time would give the correct result, regardless of the post order in the database.

      In my situation, topic_id 25 (post_id 73) has a message time of 1460449200, but topic_id 4 (post_id 16) has the newest message time of 1485184800 (2 years newer). However, post_id 73 is always calculated as the last post (until a brand new post in the forum is made).

      As a test, I changed the post_id from 16 to 2000 and synchronized the forum. The last post then displayed correctly (post_id 2000).

      This bug does not create big issues - just cosmetic/annoyance type problems. This bug becomes invisible once a new post in the forum is made after a database import (largest post_id is the newest time).

      I am willing to test code, as my migration to phpBB is still in process (not live).
