Unix Timestamp Converter Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) since January 1, 1970 UTC (the Unix epoch), commonly used to represent time in systems and APIs.
Should I use seconds or milliseconds?
APIs and databases vary: some store seconds (10 digits), others store milliseconds (13 digits). Select the correct unit to get accurate conversions.
How do UTC and local time differ here?
UTC shows the absolute time independent of your timezone. Local time adjusts the timestamp according to your device's timezone settings.
Conversion Tips
- 10-digit values are usually seconds; 13-digit values are usually milliseconds
- Use ISO format (YYYY-MM-DDTHH:mm:ssZ) for precise parsing
- When in doubt, toggle UTC vs Local to compare outputs
