Have you ever wanted to time travel. Well your in luck I have the datapack for you. Drop a clock into a minecart* to time travel. Then it will become a time machine. When you are inside, on your actionbar it will say "To Time Travel say /trigger Time set <time>". If you type /trigger Time set + a time, it will take you to that time.

This datapack removes nether portals and instead type /trigger Time set -99999 to travel to the nether inside your time machine.

Here are all the dimensions, and a brief description:

Nether (-9,999,999,999 to -10,000) - The Nether
Roofless Nether (-9,999 to -5000) - The Nether but without a roof + water, stone, and deserts
Limbo (-4999 to -2000) - Overworld Terrian but with nether biomes/fog (no overworld structures) - Some overworld biomes
Dry Overworld (-1999 to -500) - Limbo but no nether fog
