Etymology: "Outdated" is a plain formation: the verb "outdate," meaning to make something obsolete or to put it out of date, with the "-ed" ending that turns it into an adjective describing something that has been superseded. The pattern is the same as "outgrown" or "outmoded," where "out-" signals being surpassed or left behind, and the second half supplies the sense of a fixed point in time. The word therefore literally describes something that has fallen out of the current date, which is exactly how it is used today to dismiss a practice or device that newer ones have replaced.
