+ * @description
+ * Returns the number of milliseconds in the specified, years, months, weeks, days, hours, minutes and seconds.

+ * > Leap year occures every 4 years, except for years that are divisable by 100 and not divisable by 400.
+ * > 1 mean year = (365+1/4-1/100+1/400) days = 365.2425 days
+ *
+ * One month is a year divided by 12.
+ *
+ * @param {Duration} duration - the object with years, months, weeks, days, hours, minutes and seconds to be added. Positive decimals will be rounded using `Math.floor`, decimals less than zero will be rounded using `Math.ceil`.
+ * @returns {number} the milliseconds
+ * @throws {TypeError} 1 argument required

+ * @example
+ * // 1 year in milliseconds
