About Unix Timestamp Converter

Unix timestamps are used throughout software development, but they're not human-readable. This converter shows the current timestamp live, accepts timestamps or date strings as input, and displays results in multiple formats including ISO 8601, UTC, local time, and relative time.

How It Works

  1. 1

    View the current Unix timestamp at the top

  2. 2

    Enter a timestamp or date string in the Input field

  3. 3

    Click Convert to see results, or Now for current time

  4. 4

    View results in multiple formats (seconds, milliseconds, ISO 8601, etc.)

  5. 5

    Copy any result with the Copy button next to it

Use Cases

Converting API timestamps to readable dates
Debugging time-related issues
Setting expiration times
Analyzing log files with timestamps
Database timestamp conversion
Scheduling and time calculations

Frequently Asked Questions

What's the difference between seconds and milliseconds?
Standard Unix timestamps are in seconds (10 digits like 1700000000). JavaScript and some APIs use milliseconds (13 digits like 1700000000000). The tool auto-detects and handles both.
What is the Unix epoch?
The Unix epoch is January 1, 1970, 00:00:00 UTC. Unix timestamps count the seconds (or milliseconds) elapsed since this moment.
How do I handle negative timestamps?
Negative timestamps represent dates before January 1, 1970. The tool supports these for historical dates.
