From what Ive read on this site, it appears that there is a problem with some of the early timeline To start off it is noted that all three of the Sannin(Tsunade,Orochimaru and Jiraiya) became Genin around the age of 6 under the Third Hokage, Hiruzen Sarutobi, but after looking back at the Hokage's timeline it outlines and error of the years between them. As shown in flashback from Danzo, Hiruzen was made Hokage at a young age after the 2nd Hokage Tobirama chose to sacrifice himself to save his squad, and Hiruzen in this flashback looks to be around 17-19 years old but when we see him training the sannin he looks considerably older at least in his mid twenties and because Hashirama was known for spoiler Tsunade as a child(at least when she was 2 or older) and that it would only be about 4 years later that she would be under the tutelage of Hiruzen which leaves large time gap especially with the 2nd Hokage
