The setMilliseconds() method of Date instances changes the milliseconds for this date according to local time.
Syntax
setMilliseconds(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 you specify a number outside the expected range, the date information in the Date object is updated accordingly. For example, if you specify 1005, the number of seconds is incremented by 1, and 5 is used for the milliseconds.
Examples
Using setMilliseconds()
const theBigDay = new Date();
theBigDay.setMilliseconds(100);
