In this episode there is no time difference. The intro as well as the credits are not taken into consideration.

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 completely intact.
Besides that the US version had some scenes redrawn. Usually 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.
For comparisons goes:
Left: japanese version
Right: US version

Concerning this episode:
Although this episode has as many edits as the precedent episode, the censoring cuts are less. The main part of the edits are new drawn or adjusted scenes. These changes are marginal. Actually only few people would notifiy Gatou’s jacket flupping in the wind. Again these changes are little and its need is not really useful but they improve the anime’s quality.
In this episode the intro as well as the credits have not been taken into consideration, therefore there is no time difference.
