 * @name milliseconds
 * @category Millisecond Helpers
 * @summary
 * Returns the number of milliseconds in the specified, years, months, weeks, days, hours, minutes and seconds.
 *
 * @description
 * Returns the number of milliseconds in the specified, years, months, weeks, days, hours, minutes and seconds.
 *
 * One years equals 365.2425 days according to the formula:

 * > 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
 * milliseconds({ years: 1 })
 * //=> 31556952000
 *
 * // 3 months in milliseconds
 * milliseconds({ months: 3 })
 * //=> 7889238000
