📖 What is Timestamp Converter?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 (the Unix epoch). This converter translates between Unix timestamps and human-readable dates in UTC, local time and ISO 8601 format. Essential for debugging logs, APIs and database timestamps.
💡 Example
Output
Unix(s): 1716825600
UTC: Thu, 27 May 2025 16:00:00 GMT
ISO: 2025-05-27T16:00:00.000Z
Local: 5/27/2025, 12:00:00 PM
🛠️ Common Use Cases
- Debugging timestamps in API responses and logs
- Converting database datetime fields
- Understanding token expiry times in JWTs
- Comparing event timestamps across timezones
- Generating test fixtures with specific dates
❓ Frequently Asked Questions
What is a Unix timestamp? ▾
A Unix timestamp counts the number of seconds since January 1, 1970 00:00:00 UTC (the Unix epoch). It is timezone-independent and used universally in programming.
What is the difference between seconds and milliseconds timestamps? ▾
Unix timestamps in seconds are 10 digits (e.g. 1716825600). JavaScript uses milliseconds which are 13 digits (e.g. 1716825600000). Always check which your system uses.
What is the 2038 problem? ▾
32-bit systems store timestamps as signed integers. In January 2038, they will overflow and reset to 1901. Modern 64-bit systems are not affected.
How do I get the current timestamp in code? ▾
JavaScript: Date.now() (ms) or Math.floor(Date.now()/1000) (s). Python: import time; time.time(). Linux: date +%s
