AO3 is probably the best place. There are various filters you can use. For example, you can sort the stories by popularity, kudos received, or date updated. Another option is Wattpad. Although it has a more diverse range of stories in terms of quality, you can still find some really good Harry Potter time - travel fanfictions if you dig a bit.

Also, seeing how the characters adapt to the different time periods, like how they deal with the different social norms and magic that might be more or less advanced than their own time, is really interesting. It can lead to some really creative plotlines and character growth.
