A browser-based Unix timestamp converter is a free alternative that turns epoch seconds into a readable date, and back, entirely on your own device. It uses your computer's clock and time zone, needs no account, and works offline once the page has loaded.
Converting a Unix timestamp is a calculation based on your own machine's clock and time zone, so it is naturally something a browser can do without any server. A client-side converter takes an epoch value and shows the corresponding date and time, and takes a date and gives you the epoch value, all in the page you have open.
Because the conversion is local, it is instant and works whether or not you have a connection, which is convenient when you are debugging logs on a locked-down network. There is no account and nothing to send anywhere; you paste the timestamp from a log or a database and read the human-friendly date immediately.
