UE5 Real Time Clock UI

What You Will Build

By the end of this tutorial, your Unreal Engine project will show a live clock on screen using your computer’s current real world time. The clock can be used inside a HUD, debug overlay, simulation interface, menu screen, in-game dashboard, or any UI where local time is useful.

The system includes:

• A dedicated Widget Blueprint for the clock UI
• A Text Block used to display the time
• A binding function that reads the current system time
• The Now node to get real world DateTime data
• A Format Text node to display hour, minute, and second
• Character Blueprint logic that creates the widget on Begin Play
• A working in-game clock visible on the viewport

When This Clock System Is Useful

A real time clock may look like a small UI feature, but it is useful in more projects than beginners usually expect. It is not only for games. Unreal Engine is also used for simulations, training tools, dashboards, architectural visualization, and interactive presentations.

You can use this system for:

• Simulation dashboards
• Training software made in Unreal Engine
• Architectural visualization interfaces
• Debug HUDs during development
• Real world monitoring tools
• Menu screens that show local time
• Live event style UI panels
• In-game computers, terminals, or control room displays

For games, this is useful when you want the UI to reflect the player’s local machine time instead of an internal game time system. If you want a fantasy day and night cycle or simulated in-game clock, that is a separate system. This tutorial specifically displays real world system time.

Real World Clock vs Game Time Clock

Before building the widget, it is important to understand the difference between a real world clock and a game time clock.

Real World Clock

A real world clock reads the current system time from the machine running the game. If the player’s computer says the time is 14:25:09, the UI shows that time. This is useful for dashboards, debug tools, simulations, and UI panels that need to reflect local time.

Game Time Clock

A game time clock is controlled by gameplay logic. For example, a survival game may make one in-game day last twenty minutes. In that case, you would create your own time variable and advance it using timers or game state logic.

This tutorial covers a real world clock using Unreal Engine DateTime nodes. Do not confuse it with a simulated day and night system.

Create the Clock Widget Blueprint

First, create the UI widget that will display the clock.

1. Open the Content Drawer.
2. Right click in your desired UI folder.
3. Select User Interface.
4. Choose Widget Blueprint.
5. Select User Widget.
6. Name it WBP_HUD_Clock.
7. Open the widget.

The name WBP_HUD_Clock is clear because it tells you three things immediately:

• WBP means Widget Blueprint.
• HUD means it is intended for on-screen gameplay UI.
• Clock explains the purpose of the widget.

Clean naming matters. When your project grows, random names like Widget1 or ClockTestFinal2 become messy fast. A readable naming convention makes your UI system easier to maintain.

Add the Canvas Panel and Text Block

Inside WBP_HUD_Clock, create a simple layout for the clock.

1. Open the Palette.
2. Search for Canvas Panel.
3. Drag the Canvas Panel into the widget hierarchy if it is not already there.
4. Search for Text Block.
5. Drag the Text Block into the Canvas Panel.

The Canvas Panel gives direct control over where the clock appears on screen. For a small HUD clock, this is usually enough. You can place it in the top left, top right, bottom corner, or anywhere else depending on your UI design.

Select the Text Block and adjust the appearance:

• Set the font size to around 35.
• Move the text to the desired screen position.
• Set the text color to something readable.
• Enable Is Variable.
• Rename it to TextBlock_Clock.

Enabling Is Variable lets you reference the Text Block from Blueprint logic later if needed. In this tutorial, the clock is driven through a binding, but naming the widget properly is still good practice.

Compile and save before continuing.

Create a Text Binding for the Clock

Now the Text Block needs to display dynamic time instead of placeholder text.

1. Select TextBlock_Clock.
2. In the Details panel, find the Text property.
3. Click the binding dropdown.
4. Select Create Binding.

Unreal will create a binding function. This function determines what text should be displayed by the Text Block.

For a beginner tutorial, binding is the easiest way to make a clock work quickly. For larger production UI, you may prefer updating the text through a timer instead of a binding, because bindings can be evaluated frequently. For a small real time clock, this method is simple and acceptable.

Get the Current System Time

Inside the binding function, add the Now node.

The Now node returns the current local DateTime from the system running the game. That DateTime includes values such as:

• Year
• Month
• Day
• Hour
• Minute
• Second
• Millisecond

For this clock, you only need:

• Hour
• Minute
• Second

After adding Now, break the DateTime value so you can access the individual components. Then use those values to build the final clock text.

Format the Clock Text

Add a Format Text node. This node lets you build clean text output using placeholders.

Use this format:

{Hour}:{Minute}:{Second}

After typing this format, Unreal automatically creates input pins named:

• Hour
• Minute
• Second

Connect the matching DateTime values into these pins:

• Hour output to Hour
• Minute output to Minute
• Second output to Second

Then connect the formatted text to the return value of the binding function.

This gives you a visible clock like:

14:25:09

Depending on how the values are converted to text, single digit minutes or seconds may appear without a leading zero. For example, you may see 14:5:3 instead of 14:05:03. For a quick beginner tutorial, this is acceptable. For a polished UI, add leading zero formatting.

Optional Polish: Add Leading Zeros

A production clock should usually display time as:

09:04:07

Not:

9:4:7

The beginner method is enough to teach the concept, but if you want a cleaner result, format each value so it always uses two digits.

In Blueprint, you can handle this by converting each number to text and adding simple conditional logic:

• If Hour is less than 10, prefix it with 0.
• If Minute is less than 10, prefix it with 0.
• If Second is less than 10, prefix it with 0.

That small improvement makes the clock look much more professional.

Add the Clock Widget to the Viewport

The widget exists, but it will not appear in the game until you create it and add it to the viewport.

Open your Character Blueprint, usually BP_ThirdPersonCharacter.

1. Go to the Event Graph.
2. Find or create Event Begin Play.
3. Drag from Begin Play and add Create Widget.
4. Set the widget class to WBP_HUD_Clock.
5. From the Return Value, call Add to Viewport.
6. Compile and save.

Now the clock widget will be created automatically when the game starts.

Test the Real Time Clock

Press Play. You should see the current real world time displayed in your game UI.

If everything is connected correctly, the displayed time should update while the game is running.

If you do not see the clock, check these common issues:

• Make sure the widget is added to the viewport.
• Make sure the Text Block has a valid binding.
• Make sure the binding returns the formatted text.
• Make sure the text color is visible against the background.
• Make sure the Text Block is inside the visible area of the Canvas Panel.

Blueprint Logic Summary

The widget binding logic is:

Now
Break DateTime
Format Text: {Hour}:{Minute}:{Second}
Return formatted text

The Character Blueprint logic is:

Event Begin Play
Create Widget: WBP_HUD_Clock
Add to Viewport

That is the entire beginner version. It is simple, readable, and easy to expand.

Binding Method vs Timer Method

The tutorial uses a Text Block binding because it is fast and easy to understand. For beginners, this is the right teaching path.

However, if you are building a larger UI system, you should understand the tradeoff.

Binding Method

• Fast to set up
• Easy for beginners
• No extra events required
• Can be evaluated often depending on the UI

Timer Method

• More explicit control
• Can update once per second instead of constantly
• Better for performance conscious UI
• Requires a little more Blueprint setup

For a tiny clock widget, binding is fine. For a bigger HUD with many dynamic values, do not bind everything blindly. Use events or timers where possible.

How to Improve This Clock UI

The basic version works, but you can improve it in several ways.

Add AM and PM

If your audience expects a twelve hour clock, convert the hour value and add an AM or PM suffix.

Add Leading Zeros

Format hour, minute, and second as two digit values for a cleaner display.

Add Date Display

Since the Now node returns full DateTime data, you can also display the day, month, and year.

Add a Background Panel

Put the Text Block inside a Border or Overlay with a semi transparent background so it stays readable on bright scenes.

Update Once Per Second

Instead of using binding, use a timer that updates the Text Block every one second. This is cleaner for production HUDs.

Create a Reusable Clock Widget

Expose display options such as show seconds, show date, twenty four hour mode, and text color. Then the same widget can be reused across multiple menus or levels.

Common Problems and Fixes

The Clock Does Not Appear

Check whether Create Widget and Add to Viewport are connected to Event Begin Play. If the widget is never added to the viewport, it will never appear.

The Text Does Not Update

Make sure the Text Block content is bound to the correct binding function and the function returns the formatted text.

The Clock Is Invisible

Check text color, opacity, font size, and screen position. A white clock on a bright sky background may technically be there but unreadable.

The Time Format Looks Messy

Add leading zero logic so single digit values appear as 01, 02, and so on.

The Clock Shows Computer Time Instead of Game Time

That is expected. This tutorial uses real world system time. If you want simulated in-game time, create your own time variable and advance it based on gameplay rules.

Frequently Asked Questions

Does this clock show real world time?

Yes. This setup uses the Now node, which returns the current system time from the player’s machine.

Can I use this in Unreal Engine 5.5, 5.6, or 5.7?

Yes. This is a basic Widget Blueprint and DateTime workflow, so it should work across modern Unreal Engine 5 versions.

Do I need C++ for this clock?

No. This tutorial uses Blueprints only.

Can I show the date too?

Yes. Break the DateTime output from the Now node and use the day, month, and year values in your Format Text node.

Why does the clock not show leading zeros?

The beginner format uses raw integer values. To show leading zeros, add formatting logic so values below 10 are displayed with a zero prefix.

Is binding the best way to update the clock?

Binding is fine for a beginner tutorial and a small widget. For a more optimized production UI, update the text once per second using a timer.

Can I use this for an in-game day and night clock?

Not directly. This displays real world system time. For a day and night cycle, you should create a separate game time variable and update it based on your gameplay rules.

Conclusion

You now have a working real time clock in Unreal Engine 5 using Blueprints. The system uses a Widget Blueprint, Text Block binding, the Now DateTime node, Format Text, and simple viewport creation logic from the Character Blueprint.

This is a small tutorial, but the concepts are valuable. Once you understand how to pull dynamic values into UI, you can apply the same pattern to health, stamina, ammo, score, timers, debug data, inventory values, and many other HUD elements.
