Date.prototype.setSeconds()
The setSeconds() method sets the seconds for a specified
date according to local time.
Syntax
setSeconds(secondsValue)
setSeconds(secondsValue, msValue)
Parameters
secondsValue- : An integer between 0 and 59, representing the seconds.
msValueoptional- : Optional. A number between 0 and 999, representing the milliseconds.
Return value
The number of milliseconds between 1 January 1970 00:00:00 UTC and the updated date.
Description
If you do not specify the msValue parameter, the value returned
from the Date.prototype.getMilliseconds() method is
used.
If a parameter you specify is outside of the expected range, setSeconds()
attempts to update the date information in the Date object accordingly.
For example, if you use 100 for secondsValue, the minutes stored
in the Date object will be incremented by 1, and 40 will be used for
seconds.
