About these units
The second is the SI unit of time. 1 second = 1,000 milliseconds, 1 minute = 60 seconds, 1 hour = 60 minutes = 3,600 seconds and 1 day = 24 hours = 86,400 seconds. Programming APIs use milliseconds (JavaScript's Date.now(), timeouts) or seconds (Unix timestamps), so mixing them up is a common off-by-1,000 bug. Days with a daylight saving change last 23 or 25 hours; this converter uses fixed 24-hour days.
