Frequently asked questions
What is a Unix timestamp?
The number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch), not counting leap seconds. It is the most common way to store points in time in software.
Is my timestamp in seconds or milliseconds?
JavaScript and Java often use milliseconds (13 digits today), while most Unix tools use seconds (10 digits). This converter detects the length automatically and handles both.
Does the converted date use my local timezone?
Yes. The same timestamp is displayed in your browser's local timezone and in UTC, so you can use whichever your context requires.
