If Harry Potter trains in the Time Chamber in fanfiction, he might discover new magical abilities that he didn't know he had. The Time Chamber is a place full of possibilities.

He could also train his physical strength and endurance, which are often overlooked in magic training. This would make him a more well - rounded wizard, better equipped to face the challenges ahead.

One possible plot could be that Flitwick focuses on teaching Harry advanced charm spells.
