"Precise YouTube Time Ago is a Chrome extension that replaces the generic 'X time ago' format (such as 'X minutes ago,' 'X hours ago,' 'X days ago,' or 'X years ago') on YouTube with a more accurate and precise timestamp based on the actual upload date. Whether it's days, weeks, months, or years, you’ll get a clearer and more exact understanding of when a video was uploaded. Ideal for users who prefer a detailed and accurate timeline of YouTube content, eliminating vague time references and enhancing your browsing experience."
This version should cover the full range of "X time ago" formats.
