secondsValue
, and msValue
parameters,
the values returned from the getUTCMinutes()

are used.
If a parameter you specify is outside of the expected range, setUTCHours()
attempts to update the date information in the Date

, the minutes will
be incremented by 1 (minutesValue + 1
), and 40 will be used for seconds.
