What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC). It's widely used in programming and databases to represent dates and times.

Does it support different timezones?

Yes. You can convert timestamps to and from different timezones, including UTC and your local timezone.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds are 10 digits (e.g., 1709078400). Millisecond timestamps are 13 digits (e.g., 1709078400000). JavaScript's Date.now() returns milliseconds, while most Unix systems use seconds.

What is the Year 2038 problem?

Systems using 32-bit signed integers for Unix timestamps will overflow on January 19, 2038. Modern systems use 64-bit integers which extend the range far beyond practical need. This tool handles dates well beyond 2038.

Can I get the current timestamp?

Yes. The tool displays the current Unix timestamp which updates automatically. You can copy it instantly for use in your code or API calls.

How do I convert ISO 8601 dates?

Enter an ISO 8601 date string (like 2024-03-15T10:30:00Z) and the tool converts it to a Unix timestamp. It handles both UTC (Z suffix) and timezone offset formats.

About Timestamp Converter

The ZamDev Timestamp Converter translates between Unix timestamps (epoch time) and human-readable dates with full timezone support. Unix timestamps are the universal time format used in programming, databases, and APIs — representing seconds elapsed since January 1, 1970 (UTC). Enter a timestamp to see the date, or pick a date to get the timestamp. Essential for debugging time-related issues in applications.

How It Works

1Enter a Unix timestamp (seconds since epoch) to see the human-readable date.
2Or select a date and time to calculate the corresponding Unix timestamp.
3Toggle between UTC and your local timezone.
4View the timestamp in multiple formats: seconds, milliseconds, and ISO 8601.
5Copy any format to your clipboard with a single click.
