This diff has the signature generated from ~~~~ to [[Benutzer:Gestumblindi|Gestumblindi]] 11:23, 6. Jun. 2017 (CEST). This is UTC 2017-06-06T09:23:--. But the revision history timestamp shows 2017-06-06T09:26:56. There is a difference of three to four minutes.
If this is an issue due to a database lag then the entry into the database _should convey the real edit timestamp_ and not the system timestamp of the database or whereever the wrong timestamp is coming from.
This issue occurs many times the day.
