How to Evolve Eevee into Umbreon and Espeon in Pokémon Legends: Arceus

All Eevee happenings are in Pokémon Legend: Arceusand Umberon and Espeon have the same evolutionary methods as the Pokémon series game.
The only way to evolve Eevee into Umbreon or Espeon without the space-time distortion is to max out their friendship at different times of day.
For Espeon, it has to be friendship to the max and grow during the day, which is easy to do with Legend: Arceus because the Pokéball next to Eevee will flash when it’s ready to evolve. Just make sure it’s daytime and evolve it, and it will turn into an Espeon. The same is true for Umbreon, except it must evolve at night. You can check your Pokémon’s friendship level at any time with Friendship test.
To manipulate time so you can make sure your Eevee turns into the correct evolution, there are a few things you can do. Time flies faster outside the settlement, Jubilife Village time stays still, and you can always make time pass faster by sleeping in the camp.
Camps allow you to rest for a short amount of time, and can easily be used to manipulate time if you want to get Espeon and Umbreon out of your Pokédex quickly. The camps are located outside the villages, and you can also use your quarters in the Jubilife Village to rest.
