LinkedIn Post Date Extractor
A Chrome extension that decodes the Snowflake ID hidden in every LinkedIn URL, turning "2h ago" into the exact date and time.
LinkedIn only ever shows relative time ("2h ago", "3d ago"), which hides the moment something was actually posted. This extension decodes the Snowflake ID that LinkedIn bakes into every post and comment URL and turns it back into an exact, to-the-second timestamp.
Built as a Manifest V3 Chrome extension in vanilla JavaScript: a popup analyzer takes any LinkedIn post or comment URL and returns its real date and time, plus the gap between a post and each reply, for journalists checking timelines, recruiters judging how fresh a listing is, or anyone who needs to know exactly when, not roughly when.
