The setUTCMilliseconds() method of Date instances changes the milliseconds for this date according to universal time.
Syntax
setUTCMilliseconds(millisecondsValue)
Parameters
millisecondsValue- : An integer between 0 and 999 representing the milliseconds.
Return value
Changes the Date object in place, and returns its new timestamp. If millisecondsValue 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 a parameter you specify is outside of the expected range,
setUTCMilliseconds() attempts to update the date information in the
Date object accordingly. For example, if you use 1100 for
millisecondsValue, the seconds stored in the Date
object will be incremented by 1, and 100 will be used for milliseconds.
Examples
Using setUTCMilliseconds()
const theBigDay = new Date();
theBigDay.setUTCMilliseconds(500);
