Add New Users/ Change Post Timestamp

There is an easier way.

If you delete the Reply, its timestamp won’t change when you change the Topic’s timestamp.

Therefore, to get the timestamp you want:

  1. Delete the Reply
  2. Change the timestamp of the Topic so that the time difference between the OP and the Reply is what you want.
  3. Undelete the Reply
  4. Change the Topic timestamp back to what it was originally
  5. Voila!
