Date.prototype.setUTCMilliseconds()

The setUTCMilliseconds() method sets the milliseconds for a specified date according to universal time.

dateObj.setUTCMilliseconds(millisecondsValue)

millisecondsValue

A number between 0 and 999, representing the milliseconds.

The number of milliseconds between 1 January 1970 00:00:00 UTC and the updated date.

If a parameter you specify is outside of the expected range, setUTCMilliseconds() attempts to update the date information in the Date object accordingly. For example, if you use 1100 for millisecondsValue, the seconds stored in the Date object will be incremented by 1, and 100 will be used for milliseconds.

var theBigDay = new Date();
theBigDay.setUTCMilliseconds(500);
