Frequently Asked Questions
What is a Unix timestamp?
It's the number of seconds (or milliseconds) that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch) — a common way computers represent a point in time as a single number.
Does this tool support millisecond timestamps?
Yes — if your timestamp is longer than 10 digits, it's automatically treated as milliseconds instead of seconds.
Why does the date shown depend on my timezone?
The 'Local' row uses your browser's local timezone, while 'UTC' and 'ISO 8601' are timezone-independent — useful for comparing timestamps across different locations.
