There have been errors where the clocks on the database server and web server aren't exactly in sync, leading to issues where something was posted "-3 seconds ago", so this could be something like that.
Also, look at the times - it was locked 42 seconds ago, but the rest happened 1 second earlier, at 43 seconds ago. So it was really locked after the post was closed and migrated. This is corroborated by the revision history:
