About Unix timestamps

Unix timestamps are a single number that uniquely identifies a moment in time independent of timezone. The picker on the right shows your local time; the timestamp is always UTC seconds.

  • Unix time counts seconds since 1970-01-01 UTC.
  • 10 digits is seconds, 13 digits is milliseconds.
  • Negative values represent dates before 1970.
  • Always store in UTC; format for display.
