millisecond intervals

This "library" provides the following constants:

• millisecond = 1;
• second = 1000 * millisecond;
• minute = 60 * second;
• hour = 60 * minute;
• day = 24 * hour;
• week = 7 * day;

So you can do easy to read math on your dates!

import { day, week } from "msecs";

const now = new Date();
const tomorrow = new Date(now + day);
const inTwoWeeks = new Date(now + 2 * week);
const midnight = new Date(now - (now % day) + 1 * day);
