    Date.prototype.setHours()

    Summary

    The setHours() method sets the hours for a specified date according to local time, and returns the number of milliseconds since 1 January 1970 00:00:00 UTC until the time represented by the updated Date instance.

    Syntax

    dateObj.setHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])

    Versions prior to JavaScript 1.3

    dateObj.setHours(hoursValue)

    Parameters

    hoursValue
    An integer between 0 and 23, representing the hour.
    minutesValue
    Optional. An integer between 0 and 59, representing the minutes.
    secondsValue
    Optional. An integer between 0 and 59, representing the seconds. If you specify the secondsValue parameter, you must also specify the minutesValue.
    msValue
    Optional. A number between 0 and 999, representing the milliseconds. If you specify the msValue parameter, you must also specify the minutesValue and secondsValue.

    Description

    If you do not specify the minutesValue, secondsValue, and msValue parameters, the values returned from the getMinutes(), getSeconds(), and getMilliseconds() methods are used.

    If a parameter you specify is outside of the expected range, setHours() attempts to update the date information in the Date object accordingly. For example, if you use 100 for secondsValue, the minutes will be incremented by 1 (minutesValue + 1), and 40 will be used for seconds.

    Examples

    Example: Using setHours()

    var theBigDay = new Date();
    theBigDay.setHours(7);
