A few useful answers

Are timestamps seconds or milliseconds?

Both conventions exist. Choose the correct unit rather than guessing; the same number produces very different dates.

Which timezone does the date input use?

The date and time input uses your browser's local timezone. Output also includes UTC for comparison.
