What this cannot tell you

  • Everything is shown in UTC so the answer reads the same for everyone. Your local time depends on your timezone and is deliberately not the headline figure.
  • A bare number is read as seconds unless it is large enough to only make sense as milliseconds. If yours is ambiguous, include units or a date.
