Date.prototype.setTime()
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The setTime() method of Date instances changes the timestamp for this date, which is the number of milliseconds since the epoch, defined as the midnight at the beginning of January 1, 1970, UTC.
Try it
const launchDate = new Date("July 1, 1999, 12:00:00");
const futureDate = new Date();
futureDate.setTime(launchDate.getTime());
console.log(futureDate);
// Expected output: "Thu Jul 01 1999 12:00:00 GMT+0200 (CEST)"
const fiveMinutesInMs = 5 * 60 * 1000;
futureDate.setTime(futureDate.getTime() + fiveMinutesInMs);
console.log(futureDate);
// Expected output: "Thu Jul 01 1999 12:05:00 GMT+0200 (CEST)"
// Note: your timezone may vary
Syntax
js
setTime(timeValue)
Parameters
timeValue-
An integer representing the new timestamp — the number of milliseconds since the midnight at the beginning of January 1, 1970, UTC.
Return value
Changes the Date object in place, and returns its new timestamp. If timeValue is NaN (or other values that get coerced to NaN, such as undefined), the date is set to Invalid Date and NaN is returned.
Examples
Using setTime()
js
const theBigDay = new Date("1999-07-01");
const sameAsBigDay = new Date();
sameAsBigDay.setTime(theBigDay.getTime());
