Disclaimer — read before you trust the digits

Last updated: October 2026

UnixFlux is a Unix timestamp converter: it converts Unix timestamps to UTC and local time and back, supporting seconds, milliseconds and microseconds, plus batch parsing and six world time zones. In practice, it detects the unit from the magnitude of the number, since a seconds value is ten digits and a milliseconds value is thirteen, then formats it in the selected zone so a log line and a local clock can be compared directly. This page should be read with that tool in mind, because the limits described apply to what it computes.

Everything the tool works with — the timestamps you paste — is handled locally. It is usually reached for things like batch-converting a column of epoch values, and because nothing is transmitted a visitor can close the tab knowing no copy was made anywhere.

What this site is — and is not

unixflux.com is an informational site. What UnixFlux produces are estimates of a calculation, not measured facts and not professional guidance.

Output you are expected to check

A developer tool generates a draft. Whatever UnixFlux emits — a type, a formatted document, a converted value — should be reviewed and tested against your own requirements before it is used anywhere that matters.

No warranty

For UnixFlux, the assumption that matters is that your input sits inside the range the tool is built for. It detects the unit from the magnitude of the number, since a seconds value is ten digits and a milliseconds value is thirteen, then formats it in the selected zone so a log line and a local clock can be compared directly. Beyond that range — and wherever rounding, unit handling or browser rendering intrudes — the Site carries no warranty at all.
