Because Discord localises timestamps for every viewer, everyone in a server sees the same moment in their own local time - useful for scheduling raids, streams, launches, classes and community events across timezones. It also outputs the raw Unix seconds value. No sign-up, no install, and it runs entirely in the browser.
