What Is a Unix Timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970. It is a compact, timezone-independent way to represent a point in time and is widely used in databases, APIs, and log files.
Common Uses
- Debugging API responses that return timestamps as integers
- Converting log file timestamps to readable dates
- Generating expiry times for tokens or cookies
- Comparing two timestamps to calculate a duration
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or Epoch time) is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 at 00:00:00 UTC. It's a standard way to represent dates and times in computing, especially in programming and databases.
How do I convert a timestamp to a date?
Paste the Unix timestamp into the input field. The tool automatically detects whether it's in seconds or milliseconds and converts it to a human-readable date and time in your local timezone and UTC. It also shows the relative time (e.g., '2 hours ago').
How do I convert a date to a timestamp?
Enter a date in a recognizable format (e.g., '2024-01-15', 'Jan 15 2024', or '15/01/2024'). The tool parses the date and displays the corresponding Unix timestamp in both seconds and milliseconds.
What's the difference between seconds and milliseconds?
Unix timestamps in seconds are 10 digits long (e.g., 1705315200). Timestamps in milliseconds are 13 digits (e.g., 1705315200000). JavaScript typically uses milliseconds, while many other systems use seconds. This tool handles both automatically.
When does the Unix timestamp overflow?
The 32-bit signed integer limit is January 19, 2038 (the 'Year 2038 problem'). However, modern systems use 64-bit timestamps, which won't overflow for billions of years. This tool supports dates far into the future and past.
Is this tool secure?
Yes. All conversion happens entirely in your browser. Your timestamps and dates are never sent to any server. For timestamp data from logs or APIs, this local processing ensures your information stays private.
