Why is the time in Kugane the same as in Eorzea?

In the case of FFXIV, or any Final Fantasy game for that matter, the world is not a sphere, it's map is more like a toroid (donut) even though the planet is clearly a sphere shape. Until we see someone go off the west/east and come back on the other side, we don't know if Eorzea is 4 miles or 4000 miles. The scale of La Noscea to Gridania says it's maybe equal to 4 miles. So Kugane may be 8 miles away and ships only move at 1mph or perhaps realisticly they are close enough to still face the same part of the star, hence they are the same time, which was the point I was making.

We can go Game Theorist on this, as we have a means to measure it. Set-down skills, like Asylum, have a radius using a measurement particular in the game that is similar to a measurement in real life. If someone were bored enough, or interested enough, they could figure out a rough minimal size of Hydaelyn.
