Timestamp best practices
Mind seconds vs milliseconds, convert to UTC for comparisons and document the time zone explicitly.
Frequently asked questions
Seconds or milliseconds?
Unix seconds have 10 digits (e.g. 1718640000), milliseconds 13 digits (e.g. 1718640000000); mind the right format.
How do I convert to UTC?
The converter shows UTC and local time in parallel; for comparisons and storage UTC is the safe choice.
What is ISO 8601?
A standardized date format like 2025-06-17T14:00:00Z that is unambiguous and easy to sort.
Are my inputs sent anywhere?
No, the conversion runs locally in the browser.
