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)

The Year 2038 problem occurs when 32-bit systems overflow on January 19, 2038. Check if your timestamps are affected and learn about migration strategies to 64-bit systems.

What is the Year 2038 Problem?

The Year 2038 problem (Y2038 or Unix Millennium Bug) occurs when 32-bit systems can no longer represent time after 03:14:07 UTC on January 19, 2038. At this point, the 32-bit signed integer overflows, potentially causing system failures.

⚠️ Critical Dates:

  • • Maximum 32-bit timestamp: 2,147,483,647 (January 19, 2038, 03:14:07 UTC)
  • • Overflow point: Next second becomes December 13, 1901
  • • Solution: Migrate to 64-bit systems (safe until year 292,277,026,596)

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.
