setHours Method (JScript 5.6) 

  • Article

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


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

Arguments

  • 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.

Remarks

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 optional, but not specified, JScript 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.

Example

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.

}
