There was no time difference in this episode, differences due to another opening and ending are not counted.

On September 10th in 2005 the smash hit anime "Naruto" started airing in the "Toonami" program of Cartoon Network. However, for a lower rating some edits were necessary.
Yet, the level of editing is really moderate (especially compared to the german which contains almost not a single drop of blood and is also otherwise HEAVILY censored). Usually it's just that some blood has been removed or reduced, the fights itself are usually completly intact.
Besides that the US version had some scenes redrawn. Ususally faces of characters or other minor "mistakes" were corrected, to look more like the manga.


Of course the US version had it's own opener and ending, which was resented by many fans because it wasn't really a song, sounding as good as the original songs used for opening and ending credits. Besides that all the original names were kept, but some are spelled or pronounced not correctly.
Yet, the US version is very good - for a censored version.

About this episode: Save for one instance, the edits in this episode are barely worth mentioning - this being a scene in which Sasuke dislodges both arms of the beaten and helpless Zaku with sadistic joy.
Regardless of being only shown by shadows, this scene is among the most brutal of the series.
Instead of being censored, only the color filter is different in this scene.
