Date.prototype.getUTCMilliseconds()

A number. If the Date object represents a valid date, an integer between 0 and 999, representing the milliseconds portion of the given Date object according to universal time. Otherwise, NaN if the Date object doesn't represent a valid date.

Not to be confused with Unix epoch time. To get the total milliseconds since 1970/01/01, use the getTime() method.

The following example assigns the milliseconds portion of the current time to the variable milliseconds.

const today = new Date();
const milliseconds = today.getUTCMilliseconds();
