Timeless to the average guest, but it will technically fall somewhere post episode 7, pre-episode 9.
The rides will date it to the First Order and the presence of the MF and fact we aren't on Jaku means it needs to take place post-TFA.
I actually imagine there is a very, very specific timepoint they have in mind, while being in a completely new setting frees them up from having the closely mimic movie canon. This is Star Wars after all and the fandom will care, especially with such a contracted canonical universe right now, the land will be canon.
