About Unix Timestamps

Unix timestamp is the number of seconds since January 1, 1970, 00:00:00 UTC (Unix Epoch).

Formats:
  • Seconds: 10 digits (e.g., 1701936000)
  • Milliseconds: 13 digits (e.g., 1701936000000)
Range:
  • Min: January 1, 1970
  • Max: January 19, 2038 (32-bit)
  • Max: Year 292 billion (64-bit)

Professional Unix Timestamp Converter for Developers

Convert between Unix timestamps and human-readable dates with precision and ease. Our tool supports both seconds and milliseconds precision, multiple timezones, and various date formats for comprehensive time conversion needs.

What are Unix Timestamps?

Unix timestamps represent the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC. This standardized time format is widely used in computing systems, databases, and programming languages for consistent time representation across different platforms.

Why Use Unix Timestamps?

  • Universal time standard independent of timezone and locale
  • Efficient storage and computation in databases and systems
  • Easy comparison and arithmetic operations
  • Standardized format for API communications
  • Immune to daylight saving time complications
  • Compact representation requiring minimal storage space

Common Development Scenarios

  • Converting API response timestamps to readable dates
  • Processing server log files and debugging time-based issues
  • Setting expiration times for JWT tokens and sessions
  • Scheduling tasks and cron jobs in server environments
  • Analyzing time-series data and user activity patterns
  • Synchronizing timestamps across distributed systems

Timestamp Precision

Our tool automatically detects timestamp precision based on the number of digits. 10-digit timestamps represent seconds since epoch, while 13-digit timestamps represent milliseconds. This flexibility ensures compatibility with various systems and programming languages.

Timezone Considerations

While Unix timestamps are always in UTC, our converter allows you to view and input times in various timezones for convenience. This helps bridge the gap between UTC storage and local time display in applications.

Timestamp Questions

Seconds since January 1, 1970, UTC. It's how computers track time without worrying about timezones, daylight saving, or date formats. Every language and system speaks it.

10 digits = seconds (classic Unix). 13 digits = milliseconds (JavaScript, Java, most modern APIs). This tool detects which you've got automatically.

Timestamps are always UTC. This tool shows both UTC and your local time. When storing time, stick with timestamps β€” convert to local only when displaying to users.

32-bit signed integers overflow on Jan 19, 2038. If you're still running 32-bit systems by then, you'll have bigger problems. 64-bit systems are fine for the next few billion years.
