If it is I have seen a few episode of it, one of them being the time the league travelled to WWII to correct an altered timeline.

Yes this is it! The WWll Episode you are mentioned was good but there but nothing compared to some of the other episodes of this series. Especially the later seasons of the show, renamed Justice League Unlimited", are full of masterpieces.
