A Unix timestamp (also called epoch time) represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC — known as the Unix epoch. This universal reference point provides a timezone-independent way to represent dates and times. It is the standard time format used in most programming languages, databases, and APIs.
The tool automatically detects whether your input is in seconds (10 digits, e.g., 1700000000) or milliseconds (13 digits, e.g., 1700000000000). Seconds-based timestamps are used by Unix systems and most backend languages, while milliseconds are common in JavaScript (Date.now()) and Java (System.currentTimeMillis()). Both formats are fully supported.
Yes, you can convert timestamps between any timezone worldwide. The tool displays the converted date in UTC and your local timezone by default, with the option to select any IANA timezone. This is essential for debugging time-related issues in distributed systems that operate across multiple time zones.
