The setSeconds() method of Date instances changes the seconds and/or milliseconds for this date according to local time.
Syntax
setSeconds(secondsValue)
setSeconds(secondsValue, msValue)
Parameters
secondsValue- : An integer between 0 and 59 representing the seconds.
msValue- : An integer between 0 and 999 representing the milliseconds.
Return value
Changes the Date object in place, and returns its new timestamp. If a parameter is NaN (or other values that get coerced to NaN, such as undefined), the date is set to Invalid Date and NaN is returned.
Description
If you do not specify the msValue parameter, the value returned
from the 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.
Examples
Using setSeconds()
const theBigDay = new Date();
theBigDay.setSeconds(30);
