"Time Travelers" is a manual category. You'd have to add it on the Category Box at the bottom or the one in the right side if you're using the source editor.

However, remember that Flash doesn't time travel by himself, but he uses the Speed Force to create portals and phase between time streams. I'm not entirely sure if it would be accurate to categorize him as a time traveler. I suggest you bring it up on the talk page.
