Since whoever the memorial was for died before or during 201X, then if Gaster died 201X or earlier, the CORE could not have been built after 201X.

Chara fell in 201X, and the monsters all reached New Home at the end of 201X, the date Chara arrived (Some of them left at the start of 201X, as Toriel's calendar stops there). The CORE could not have been built before this journey, because before the journey, the monsters were all living in the Ruins.

So, that means the CORE began being built in late 201X at the earliest, given that Hotland is quite late in the journey from Ruins to New Home. However, given that the monsters were simply looking to reach their New Home, the odds of them building the CORE in the meantime would be quite low.

The CORE must have began its construction after 201X, or very late 201X. It would not have been finished before the year ended. Gaster would have not finished his construction.

The CORE was built after 201X. So Gaster was alive after 201X. So the memorial couldn't have been for him.

So, another hypothesis is gone.

..Wait, there was a hotel complex built in 201X. If it was after, the fountain couldn't have been made IN the hotel, and it couldn't have been before, since the monsters didn't start their journey until 201X. This does appear to mean that some monsters did settle on as the journey went on. Which does appear to match what Monster History, Part 4 tells us.

..It also means the move HAD to have been a gradual one. Some monsters were still in the Ruins, else Asriel couldn't have found Chara. Yet the hotel was built, meaning some had went on in the journey.

Asgore likely led the expedition, as all the towns got his signature bad names, meaning Toriel was the one to stay behind with Asriel, until everything was ready for them.

..I'm not sure what this means about the CORE, however. The lore says Gaster fell into his creation. So the Core had to be been built before Gaster's fall in 201X. And the True Lab was part of that Core, because Alphys found Gaster's blueprints for the Determination Extraction machine there.

Just because Chara arrived at New Home at the end of 201X, doesn't mean that's when the monsters arrived there. Don't forget the ancient Waterfall Glyphs that talk about a time when there was no entrances or exits to the Underground, something that clearly isn't true anymore. It's been a very long time since the Barrier was cast, which is why only an ancient turle like Gerson could have lived long enough to remember the original war.

We don't know how long the monsters have been at New Home, but this capital was likely there long before Chara arrived. The tapes about Toriel and Asgore talking in puns about having a child were certainly before Chara arrived, and Alphys found those tapes in the True Lab, along with all of Gaster's other artifacts. (though how Gaster got those tapes is certainly an interesting question).

I don't think we have a firm date on when the Core was built, or when Sans and Gaster arrived in the Underground. But it was certainly in place before Chara.
