Anyone who travels aboard an starship that travels through the Warp could be a time traveler. The tides of Warp are forever in Flux, there are stories of  guardsmen and navy crews who left on their journey and exited the warp days to even centuries after they began their trip in real space time. some also arrive before they even left although that creates a paradox however the warp is a paradox. There is no control how long the journey will take only the estimates of previous travels.

A trip that by rights should be a short one can take several centuries if not more in real space, once they exit the warp their destination or whomever they were going to meet may be long dead or destroyed, and the crew and passengers may have ages only hours days or months  Time means nothing in the warp  it can flow forward or backward.

So yes Time travel is very common in the 40K universe  its just not the type of time travel one expects or plans on....
