What it does
Convert a Unix timestamp into a readable date, or pick a date and time to get its timestamp. The current Unix time ticks at the top, a Now button puts it in the input, and each result (seconds, milliseconds, ISO 8601, UTC, local time with its offset, and relative time such as "in 3 days") has its own copy button.
You do not need to say whether a value is in seconds or milliseconds: values of 100 billion or more are read as milliseconds, everything smaller as seconds. Non-numeric input gets a clear error, and the date picker stays in sync with whatever timestamp you type.
When you would reach for it
- Turn a created_at or exp value from a database row or JWT into a human-readable date.
- Get the timestamp for a specific date to use in an API filter or a SQL query.
- Check whether a value in a log is in seconds or milliseconds by seeing which reading makes sense.
- Grab the current Unix time for a test fixture or a cache expiry calculation.
