means The period of darkness between sunset and sunrise, when the part of Earth you're standing on faces away from the sun.
from A transparent compound of plain old English parts: "night" (Old English niht, a word with deep Germanic roots and cousins all across the family — German Nacht, Latin nox, Greek nyx) simply welded to "time." No mystery here; English has been stacking "night" against other words for ages, and "nighttime" is just the hours of night made tidy.
