The time when Undertale begins is currently the Present.

When I say Sans and the others are from the Past, I mean a time before Frisk/Chara reawokened. Maybe a time before the war broke out and monsters were still living on the surface. Maybe a time just after the war ended and monsters were exploring their new life underground.

What if Gaster was trying to look into the future to see if he could find a way to prevent the war from ever happening? Or to find a solution to breaking the barrier that they couldn't find in their time?
