setUTCHours Method 

Sets the hours value in the Date object using Coordinated Universal Time (UTC).

function setUTCHours(numHours : Number [, numMin : Number [, numSec : Number [, numMilli : Number]]]) 


Required. A numeric value equal to the hours value.


Optional. A numeric value equal to the minutes value.


Optional. A numeric value equal to the seconds value.


Optional. A numeric value equal to the milliseconds value.

All set methods taking optional arguments use the value returned from corresponding get methods, if you do not specify an optional argument. For example, if the numMin argument is optional, but not specified, JScript uses the value returned from the getUTCMinutes method.

To set the hours value using local time, use the setHours method.

If the value of an argument is greater than its range, or is a negative number, other stored values are modified accordingly. For example, if the stored date is "Jan 5, 1996 00:00:00.00", and setUTCHours(30) is called, the date is changed to "Jan 6, 1996 06:00:00.00."

The following example illustrates the use of the setUTCHours method.

function SetUTCHoursDemo(nhr, nmin, nsec){   
   var d, s;                        //Declare variables.
   d = new Date();                  //Create Date object.
   d.setUTCHours(nhr, nmin, nsec);  //Set UTC hours, minutes, seconds.
   s = "Current setting is " + d.toUTCString() 
   return(s);                       //Return new setting.
