Usage Tips

  • Unix timestamps are commonly 10 digits (seconds) or 13 digits (milliseconds)
  • The converter automatically detects timestamp format based on digit count
  • All conversions are performed in UTC timezone by default
  • Use ISO 8601 format for maximum compatibility across systems
  • Negative timestamps represent dates before January 1, 1970

Frequently Asked Questions

Q: What's the difference between seconds and milliseconds?

Seconds are the standard Unix timestamp format. Milliseconds include 3 additional digits for sub-second precision.

Q: Why does epoch start from 1970?

January 1, 1970 was chosen as a convenient round number close to the beginning of computing systems.

Q: What happens in 2038?

32-bit systems will experience overflow, but 64-bit systems can handle dates far beyond 2038.
