As a subject matter expert in comic book lore and superhero narratives, I can provide an informed perspective on the abilities of Superman, a character from DC Comics.

Superman, in various storylines and adaptations, has been depicted as having the ability to travel through time. This is not one of his standard powers, but it has been a plot device used on occasion. The most common way Superman has been shown to time travel is by flying around the Earth at speeds faster than light, which distorts the space-time continuum and allows him to access different time periods. This method is based on the theory of relativity, which suggests that time is affected by speed and gravity.

However, it's important to note that the ability to time travel is not a consistent feature of Superman's character across all media. In some versions, he does not possess this power at all. The portrayal of Superman's powers can vary greatly depending on the writer, the era, and the medium (comics, TV, film, etc.).
