Why does the traded Pokemon have an encounter date in the future

pokemon-x-y

I had a look at my Gyarados's summary I just got him from trade and when I had a look at where he was from, it said a faraway place (I know what that means) and the date was 2018 (I was surprised about the year and I don't know the rest of the date) how is he from 2018? It's 2017 and time machines don't exist…

How is he from/ meet in 2018? It's really weird, is it a glitch or something?

It likely means it was hacked into the game.

From a Faraway place is always related to event Pokemon, and the only event Gyarados were given away in Japan and South Korea, between 2014-2016.

Suffice to say, you have a hacked Pokemon. It will have no effect on your game or you unless you try to compete in an official tournament.
