What it does
A free Unix timestamp converter. The current epoch ticks live at the top so you can grab “right now” in one click. Paste any timestamp to see it rendered as ISO 8601, local time, UTC, and how long ago (or from now) the moment falls. Go the other direction too: pick a date and read back Unix seconds and milliseconds.
Unix timestamps are the internet’s favorite date format: timezone-agnostic, fixed-width, easy to sort. They crop up in API payloads, database columns, JWT tokens, and log lines. This tool handles both second and millisecond precision, which matters because half the world’s APIs use one and half use the other.
How to use it
- To read a timestamp: paste it and pick seconds or milliseconds.
- To get the current epoch: click Use now.
- To encode a date: enter it in the date/time field at the bottom.
- Copy any output with the per-field Copy button.
