UNB/ CS/ David Bremner/ teaching/ cs2613/ books/ mdn/ Reference/ Global Objects/ Date/ Date.prototype.setSeconds()

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

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);
