Frequently asked questions
What is a Unix timestamp?
The number of seconds that have passed since 1 January 1970, 00:00:00 UTC (the "Unix epoch"). It's a compact, timezone-free way computers store a point in time.
How does this tell seconds and milliseconds apart?
By length: a timestamp in seconds is 10 digits until the year 2286, while milliseconds is 13 digits today. This tool treats anything with 12 or more digits as milliseconds and anything shorter as seconds.
Does the converted date account for my timezone?
Both are shown: the UTC time (timezone-independent, what's actually stored) and your browser's local time, calculated from your device's own timezone setting.
