setMilliseconds Method (Date) (JavaScript)


Sets the milliseconds value in the Date object using local time.



Required. Any Date object.


Required. A numeric value equal to the millisecond value.

To set the milliseconds value using Universal Coordinated Time (UTC), use the setUTCMilliseconds method.

If the value of numMilli is greater than 999 or is a negative number, the stored number of seconds (and minutes, hours, and so forth if necessary) is incremented an appropriate amount.


The following example illustrates the use of the setMilliseconds method.

function SetMSecDemo(nmsec){
   var d, s;                    // Declare variables.
   d = new Date();              // Create Date object.
   d.setMilliseconds(nmsec);    // Set milliseconds.
   s = "Current setting is ";
   s += d.toLocaleString();
   s += " and " + d.getMilliseconds();
   s += " milliseconds";
   return(s);                   // Return new date setting.
