How would wormholes and teleportation affect the passage of time?

+0
−0

Time is not a constant, Albert Einstein proved that much. Time dilation is a difference in the elapsed time measured by two clocks, either due to them having a velocity relative to each other, or by there being a gravitational potential difference between their locations. In the vast universe we can agree about distances but not about time.

Here is my question: How would a wormhole and/or teleportation affect time between two observers on different planets? What are the dangers that need to be taken into account? How can this be taken advantage of?

There might not be a definitive answer due to the fact that we haven't invented faster-than-light travel or teleportation. But knowing this helps from a writing standpoint as it allows to know how it will affect the story if not at all. Would a traveler come back home after the exact time he spent on another planet or would he be too late? If a portal was kept open between two planets would time be a constant? If a portal is closed and then opened again will time have passed into another century? These sorts of questions.
