The setSeconds() method sets the seconds for a specified date according to local time.
dateObj.setSeconds(secondsValue[, msValue])
dateObj.setSeconds(secondsValue)
secondsValuemsValueIf you do not specify the msValue parameter, the value returned from the getMilliseconds() method is used.
If a parameter you specify is outside of the expected range, setSeconds() attempts to update the date information in the Date object accordingly. For example, if you use 100 for secondsValue, the minutes stored in the Date object will be incremented by 1, and 40 will be used for seconds.
setSeconds()var theBigDay = new Date(); theBigDay.setSeconds(30);
