Discord timestamps can be useful for specifying a date/time across multiple users time zones. They work with the Unix Timestamp format and can be posted by regular users as well as bots and applications.
The Epoch Unix Time Stamp Converter is a good way to quickly generate a timestamp. For the examples below I will be using the Time Stamp of 1543392060, which represents November 28th, 2018 at 09:01:00 hours for my local time zone (GMT+0100 Central European Standard Time).
| Style | Input | Output (12-hour clock) | Output (24-hour clock) |
|---|---|---|---|
| Default | <t:1543392060> |
