Discord timestamps work by typing a special tag directly into your message that Discord automatically converts to each viewer’s local timezone. The basic format is <t:UNIX_TIMESTAMP>;, where the Unix timestamp is the number of seconds since January 1, 1970 (UTC), and you can change how it displays by adding a style like <t:UNIX_TIMESTAMP:f> or <t:UNIX_TIMESTAMP:R>. Common styles include t for short time, d for short date, f for date and time, F for full date and time with the weekday, and R for relative time like “in 2 hours” or “3 days ago.” To get the Unix timestamp, most people just use an online converter, paste the number into the format, and send it as a normal message (not in a code block). Once sent, Discord handles the timezone conversion automatically, so everyone sees the correct time for their location.
