Date.prototype.setUTCHours()
The setUTCHours() method sets the hour for a specified
date according to universal time, and returns the number of milliseconds since January
1, 1970 00:00:00 UTC until the time represented by the updated Date
instance.
Syntax
setUTCHours(hoursValue)
setUTCHours(hoursValue, minutesValue)
setUTCHours(hoursValue, minutesValue, secondsValue)
setUTCHours(hoursValue, minutesValue, secondsValue, msValue)
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
secondsValueparameter, you must also specify theminutesValue.
- : Optional. An integer between 0 and 59, representing the seconds. If you specify the
msValue- : Optional. A number between 0 and 999, representing the milliseconds. If you specify
the
msValueparameter, you must also specify theminutesValueandsecondsValue.
- : Optional. A number between 0 and 999, representing the milliseconds. If you specify
the
Return value
The number of milliseconds between January 1, 1970 00:00:00 UTC and the updated date.
Description
If you do not specify the minutesValue,
secondsValue, and msValue parameters,
the values returned from the Date.prototype.getUTCMinutes(), Date.prototype.getUTCSeconds(),
and Date.prototype.getUTCMilliseconds() methods
are used.
If a parameter you specify is outside of the expected range, setUTCHours()
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.
