Installation

You can use the following command to install this package, or replace npm install with your package manager of choice.

npm install @sapphire/timestamp

Usage

Note: While this section uses require, the imports match 1:1 with ESM imports. For example const { Timestamp } = require('@sapphire/timestamp') equals import { Timestamp } from '@sapphire/timestamp'.

Human Readable Milliseconds

Milliseconds are often hard for humans to quickly parse, so it's nice to use named Enum members to make it easier to read.

// Import the Time enum
const { Time } = require('@sapphire/timestamp');

setTimeout(() => {
	// Do something in half a second
}, Time.Second / 2 /* 500 */);

setTimeout(() => {
	// Do something in 6 hours
}, Time.Hour * 6 /* 21600000 */);

setTimeout(() => {
	// Do something in 1 day
}, Time.Day /* 86400000 */);

Formatting a Date

// Import the Timestamp class
const { Timestamp } = require('@sapphire/timestamp');

// Saturday 9th March 2019, at 16:20:35:500
const date = new Date(2019, 2, 9, 16, 20, 35, 1);

// Format the date with tokens (use square brackets to escape)
const timestamp = new Timestamp('MMMM d YYYY[, at ]HH:mm:ss:SSS');
timestamp.display(date); // March 9th 2019, at 16:20:35:001

// Saturday 9th March 2019, at 16:20:35:500
const date = new Date(2019, 2, 9, 16, 20, 35, 1);

new Timestamp('Y').display(date); // 19
