"First of all not all of the conversastion took place inside of the time stop bubble so yeah time did in fact pass a little bit"

- Appel

The only parts that don't are the ketchup choice and Sans leaving, both of which take up so little time that the food would have to be nearly cold already for it to have gotten cold at that point.

"Also Grillby never said that, it was the bird guy at the bar who "translated" it for you cause Grillby doesn't talk and later in the game you find out the bird guy was just making stuff up."

- Appel

Which just means that the random unnamed bird guy is aware of time passing, which... is a further point in Jacky's favor.

Finally:

"wouldn't stopping time and suddenly changing the pattern of bones fuck over Frisk? Wouldn't it make it harder on him/her? Keep in mind Sans' goal is to make Frisk give up."

- Appel

This is line of reasoning is contradicted by the fight. If Sans' goal was to make Frisk give up and he had time stop, why would he stop time in an unescapable attack and not let that attack hit?

Honestly, a lot of this can be brought to Hanlon's Razor. Before and during the fight, Sans displays teleportation powers. That conversation about Flowey was done using oblique terms such that the only people who would know what he's talking about are those who already know about Flowey, which would make less sense if he's stopped time. Ergo, the simplest possible explanation for his attacks is teleportation.

Is it possible that he could be hiding his Time Stop the way Homura does? It is, but it's also possible that Sans has an infinite number of clones and isn't actually teleporting himself around the map. It's simply not probable, and is reaching incredibly hard.
