JScript Date Object setHours Method

Modifies the hours stored in the Date object according to local time.

Syntax: JScript Date Object setHours Method

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

Arguments: JScript Date Object setHours Method

objDate

The name of a Date object. Required.

numHours

A numeric value equal to the hours value. Required.

numMin

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

numSec

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

numMilli

A numeric value equal to the milliseconds value. Optional.

Remarks: JScript Date Object setHours Method

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 getMinutes method.

To set the hours value according to 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.
