setHours Method (Date) (JavaScript)

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

dateObj.setHours(numHours[, numMin[, numSec[, numMilli]]])
dateObj

Required. Any Date object.

numHours

Required. A numeric value equal to the hours value.

numMin

Optional. A numeric value equal to the minutes value. Must be supplied if either of the following arguments is used.

numSec

Optional. A numeric value equal to the seconds value. Must be supplied if the following argument is used.

numMilli

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 numMinutes argument is not specified, JavaScript uses the value returned from the getMinutes method.

To set the hours value using Universal Coordinated Time (UTC), use the setUTCHours 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", and setHours(30) is called, the date is changed to "Jan 6, 1996 06:00:00." Negative numbers have a similar behavior.

The following example illustrates the use of the setHours method.

function SetHoursDemo(nhr, nmin, nsec){
   var d, s;                     //Declare variables.
   d = new Date();               //Create Date object.
   d.setHours(nhr, nmin, nsec);  //Set hours, minutes, & seconds.
   s = "Current setting is " + d.toLocaleString() 
   return(s);                    //Return new date setting.
}
