I built a Discord Timestamp Generator with 100% Page Speed Scores (Open Source)

Disc Time Stamps — Fri, 02 Jan 2026 17:48:37 +0000

The Problem

As a Discord power user, I constantly need to generate dynamic timestamps (like <t:1735689600:R>) for event announcements.

Most existing tools have two problems:

They are loaded with aggressive ads.
They are slow and unoptimized for mobile phones.

I decided to fix this by building my own open-source alternative: DiscTimestamps.

The Tech Stack

I wanted this project to be blazing fast and completely privacy-focused.

Framework: React + Vite
Styling: Tailwind CSS
Icons: Lucide React
Hosting: Vercel/Netlify (Static)

Optimizing for Performance (Hitting 98+ on Mobile)

My goal was to hit a perfect 100 on Google Page Speed Insights. Here is how I did it:

1. Smart Lazy Loading

I used React's lazy and Suspense to split the code. If you visit the Home page, you don't download the code for the "Embed Builder" or "Emoji Downloader" until you actually click those tabs.

2. Non-Blocking Fonts

I used the font-display: swap strategy to ensure text is visible immediately, rather than waiting for the font file to download.

3. Deferring Heavy Scripts

Google Tag Manager was blocking the main thread by ~150ms. I moved it to load after the main content is interactive, using a custom delay script.

The Result

The site now scores 98-100 on Mobile Performance and 100 on Accessibility.

Features

It’s not just a timestamp generator. I expanded it into a full suite:

Timestamp Generator: With an AI parser (type "in 2 hours").
Embed Builder: Visual JSON editor for web hooks.
Emoji Downloader: Grab custom emojis easily.

Open Source

The project is 100% free and open source. You can check the code or contribute on GitHub.

Stop fighting with Time zones: A Developer's Guide to Discord Timestamps

Disc Time Stamps — Tue, 09 Dec 2025 18:54:56 +0000

Have you ever tried to organize an event on Discord, only to have half your users show up an hour late because of time zone confusion?

We’ve all been there. You say “Event starts at 5 PM EST,” but your friend in London sees “5 PM” and assumes it’s their local time.

The solution is Discord Dynamic Timestamps.

You’ve probably seen them before — those magical little tags that say “in 2 hours” or “Sunday at 4:00 PM” and automatically adjust to the reader’s local time zone.

In this guide, I’ll show you exactly how to create them manually, and the faster way to generate them automatically.

The Easy Way (Recommended)
If you don’t want to do math or memorize code, I built a free tool that does this instantly.

DiscTimestamps is a dedicated generator that:

Automatically calculates the Unix time.
Shows you a Live Preview of what the code looks like.
Let’s you click-to-copy the code in seconds.
If you prefer to do it the hard way (manually), keep reading for the syntax breakdown.

The Manual Syntax
Discord uses a specific format called Unix Timestamping. The syntax looks like this:

There are three parts to this code:

<t: – Opens the tag.
TIMESTAMP – The time in Unix format (seconds since 1970).
FLAG – A single letter that tells Discord how to display the time.
Step 1: Get the Unix Time

You cannot type “2025–12–09” into Discord. You need to convert that date into a number like 1765238400.

You can use a site like DiscTimestamps.com to get this number accurately for your specific date.

Step 2: Choose your Flag (The Cheat Sheet)

Once you have your number, you need to decide how it looks. Here is the complete list of flags supported by Discord:

Become a member
Relative Time (:R)

Code:
Result: “in 2 hours” or “5 minutes ago”
Best for: Countdowns, events, and reminders.
Short Time (:t)

Code:
Result: “4:00 PM”
Best for: Simple clock times.
Long Date (:D)

Code:
Result: “December 9, 2025”
Best for: Announcing future dates without the time.
Full Date with Short Time (:f)

Code:
Result: “December 9, 2025 4:00 PM”
Best for: The standard format for most event announcements.
Why use Relative Time (:R)?
The :R flag is the most powerful tool for a community manager. It creates a sense of urgency.

Instead of writing “Stream starts at 8 PM,” write: “Stream starts !”

This will show up as “Stream starts in 4 hours!” for everyone, regardless of where they live. As the time gets closer, the message updates itself automatically to “in 5 minutes”.

Summary
Don’t type time zones manually (EST, GMT, PST).
Do use Unix timestamps to sync your community.
Do use Discord Timestamps tool to generate these codes error-free, especially on mobile where typing brackets is annoying.
Happy gaming!
