The setMilliseconds()
method sets the milliseconds for a specified date according to local time.
dateObj.setMilliseconds(millisecondsValue)
millisecondsValue
If you specify a number outside the expected range, the date information in the Date object is updated accordingly. For example, if you specify 1005, the number of seconds is incremented by 1, and 5 is used for the milliseconds.
setMilliseconds()
var theBigDay = new Date(); theBigDay.setMilliseconds(100);
