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.
 Copy Code | |
|---|---|
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.
