The main series itself has several timeline inconsistencies, such as the timeframe of Stardust Crusaders being retconned. If you wanted to remove all timeline inconsistencies, you would need to change Josuke's age during the events of Stardust Crusaders. As described by one comment on the timeline page, Josuke would logically be 5 years old, but the manga describes him as 4, and so does this wiki. Araki is an author known for being somewhat inconsistent.
