page-type: javascript-instance-method
browser-compat: javascript.builtins.Date.setUTCSeconds
sidebar: jsref
The setUTCSeconds() method of {{jsxref("Date")}} instances changes the seconds and/or milliseconds for this date according to universal time.
{{InteractiveExample("JavaScript Demo: Date.prototype.setUTCSeconds()")}}
const date = new Date("December 31, 1975, 23:15:30 GMT+11:00");
console.log(date.getUTCSeconds());
// Expected output: 30
date.setUTCSeconds(39);
console.log(date.getUTCSeconds());
// Expected output: 39
Syntax
setUTCSeconds(secondsValue)
setUTCSeconds(secondsValue, msValue)
Parameters
secondsValue- : An integer between 0 and 59 representing the seconds.
msValue{{optional_inline}}- : An integer between 0 and 999 representing the milliseconds.
Return value
Changes the {{jsxref("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
{{jsxref("Date/getUTCMilliseconds", "getUTCMilliseconds()")}} method is
used.
If a parameter you specify is outside of the expected range,
setUTCSeconds() attempts to update the date information in the
{{jsxref("Date")}} object accordingly. For example, if you use 100 for
secondsValue, the minutes stored in the {{jsxref("Date")}} object will be
incremented by 1, and 40 will be used for seconds.
Examples
Using setUTCSeconds()
const theBigDay = new Date();
theBigDay.setUTCSeconds(20);
