Some constants for convenient amounts of time, in milliseconds

```js

const SECONDS_PER_MINUTE = 60;
const MINUTES_PER_HOUR = 60;
const HOURS_PER_DAY = 24;
const DAYS_PER_WEEK = 7;
const MONTHS_PER_YEAR = 12;

const SECOND = MILLISECONDS_PER_SECOND;
const MINUTE = SECOND * SECONDS_PER_MINUTE;
const HOUR = MINUTE * MINUTES_PER_HOUR;
const DAY = HOUR * HOURS_PER_DAY;
const WEEK = DAY * DAYS_PER_WEEK;
const YEAR = DAY * 365.24;
const NORMAL_YEAR = DAY * 365;
const LEAP_YEAR = DAY * 366;
const DECADE = 10 * YEAR;
const HALF_YEAR = YEAR/2;
const AVERAGE_MONTH = YEAR/12;
