// overview
What it does
Unix time is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Convert between epochs (s / ms / µs / ns) and ISO / RFC 2822 / human dates.
Because Hexkit is a native app rather than a web page, anything you paste into the unix time stays local — there are no uploads, no accounts and no telemetry. You can convert between formats in seconds even with the network turned off, which makes it safe for tokens, keys and production data.

How to use Unix time
- 1
Open Hexkit and select "Unix time", or press the command-palette key and start typing its name.
- 2
Paste or type the value you want to convert. Convert between epochs (s / ms / µs / ns) and ISO / RFC 2822 / human dates.
- 3
Read or copy the result. Everything is computed locally by Hexkit's Rust core, so nothing is ever uploaded.
Tip: the command palette opens any tool in one keystroke.
