Frequently Asked Questions
A Unix timestamp is the number of seconds elapsed since January 1, 1970 UTC (the 'Unix epoch'). It's the standard way computers store points in time because it's timezone-independent and easy to compare.
Second-based timestamps are currently 10 digits long, while millisecond timestamps (used by JavaScript's Date.now()) are 13 digits. The converter handles both and shows each form in its output.
The local time output uses your browser's timezone setting. The UTC and ISO 8601 outputs are timezone-independent, so use those when sharing timestamps with people in other regions.
ISO 8601 is the international standard date format, like 2026-07-02T14:30:00Z. It sorts chronologically as plain text and is unambiguous across locales, which makes it the preferred format for APIs and logs.
Yes. The relative output ('5 minutes ago', 'in 3 days') recalculates every second so it stays accurate while you work.
