Hypothetical sci-fi question about wormholes and elapsed time between the 2 points

Hi there.
I'm writing a sci-fi story for a video game.
At some point in time an advanced civilization from the future, say 4010, creates a wormhole for a not so advanced civilization spacecraft in the past, say 2050, to travel through. The idea is for the not so advanced civilization spacecraft to meet the advanced one in its own time, 4010.
The question is (theoretically and sci-fi speaking): how many years would have passed for the advanced civilization in 4010 until the not so advanced civilization spacecraft arrived?
Its possible that I'm missing some pseudo-scientific data so feel free to complement my reasoning.
I hope I made it clear.
Any help is appreciated .
Thank you.
