Frequently Asked Questions (FAQ)
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It's widely used in databases, APIs, and log files.
Does the tool support milliseconds?
Yes. Timestamps with 13 digits are automatically treated as milliseconds — common in JavaScript's Date.now().
What time zone are dates shown in?
Dates are shown in both UTC and your local browser time zone, along with other common zones like IST, PST, and EST.
All conversions happen in your browser. No timestamp data is sent anywhere.
