About Unix Timestamps

What is a Unix Timestamp?

A Unix timestamp (also known as Epoch time) is the number of time units that have elapsed since January 1, 1970 00:00:00 UTC. It's a universal time representation used in computing systems worldwide.

Common Units

  • Seconds: Standard Unix timestamp (10 digits)
  • Milliseconds: JavaScript/Java standard (13 digits)
  • Microseconds: Python/PHP precision (16 digits)
  • Nanoseconds: Maximum precision (19 digits)

Frequently Asked Questions

What's the difference between Unix timestamp formats?

Unix timestamps come in different precisions: seconds (10 digits), milliseconds (13 digits), microseconds (16 digits), and nanoseconds (19 digits). The format depends on the system and required precision.

How do I know which timestamp format to use?

Check the number of digits: 10 = seconds (Unix/Linux), 13 = milliseconds (JavaScript/Java), 16 = microseconds (Python/PHP), 19 = nanoseconds (high-precision systems).

Are Unix timestamps timezone-aware?

Unix timestamps are always in UTC (Coordinated Universal Time). When converting to a date, you can display it in any timezone, but the timestamp itself represents a single moment in time globally.
