Automatically detects the user's browser timezone and provides **Facade, Helpers, Carbon macros, Filament table/form macros, and an Eloquent trait** for seamless timezone conversion.

**Store in UTC. Display in the user's local time. Automatically.**

Features
--------

[](#features)

- **Auto browser detection** — JavaScript detects IANA timezone via `Intl.DateTimeFormat` with 10+ fallback methods
- **Livewire v4 / SPA compatible** — uses `Livewire.interceptRequest()`, `wire:navigate`, fetch/XHR interceptors, cross-tab BroadcastChannel sync
- **Middleware** — captures timezone from header, cookie, query param, or form input → stores in session
- **One-liner macros** — `TextColumn::toUserTimezone()`, `TextEntry::toUserTimezone()`, `DateTimePicker::fromUserTimezone()`
- **Carbon macros** — `$date->toUserTimezone()`, `->toSystemTimezone()`, `->formatInUserTimezone()`
- **Facade & helpers** — `TimezoneDetector::forDisplay()`, `to_user_timezone()`, `user_now()`, etc.
- **Eloquent trait** — `InteractsWithTimezone` for per-attribute conversion
- **Fully configurable** — toggle every feature on/off, customize header/cookie/session names

Requirements
------------

[](#requirements)

- PHP >= 8.2, Laravel >= 11.0, Filament >= 5.0

Installation
------------

[](#installation)

```
composer require eslam-reda-div/filament-timezone-detector
```

Register the plugin in your panel provider:

```
use EslamRedaDiv\TimezoneDetector\TimezoneDetectorPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugin(TimezoneDetectorPlugin::make());
}
```

Optionally publish the config:

```
php artisan vendor:publish --tag="timezone-detector-config"
```

**That's it.** The plugin auto-loads JS detection, registers middleware, Carbon macros, and Filament macros.

How It Works
------------

[](#how-it-works)

```
Browser (JS)                          Server (Middleware)                Your Code
─────────────                         ──────────────────                ─────────
Intl.DateTimeFormat() detects    →    Reads X-Timezone header      →   Facade / Helper / Carbon macro
timezone and sends it via:            (or cookie / query param)        converts any datetime between
• Livewire interceptRequest           Stores in session('user_tz')     user ↔ system timezone
• fetch / XHR / Axios interceptors
• Cookie + hidden form inputs
• BroadcastChannel (cross-tab)

```

**Recommended:** Store all datetimes in UTC (`config/app.php → 'timezone' => 'UTC'`). The plugin handles display conversion automatically.

Usage
-----

[](#usage)

### Filament Table Columns

[](#filament-table-columns)

```
TextColumn::make('created_at')->dateTime()->toUserTimezone(),
TextColumn::make('published_at')->dateTime('M d, Y h:i A')->toUserTimezone(),
TextColumn::make('updated_at')->since()->toUserTimezone(),
```

TextEntry::make('updated_at')->since()->toUserTimezone(),
```

### Filament Form Fields

[](#filament-form-fields)

```
DateTimePicker::make('starts_at')->toUserTimezone(),    // display + save in user TZ
DateTimePicker::make('event_time')->fromUserTimezone(),  // alias, clearer intent

### Facade

[](#facade)

```
use EslamRedaDiv\TimezoneDetector\Facades\TimezoneDetector;

// Info
TimezoneDetector::getUserTimezone();       // "America/New_York"
TimezoneDetector::getSystemTimezone();     // "UTC"
TimezoneDetector::getOffsetFromSystem();   // -4.0
TimezoneDetector::getUserUtcOffset();      // "-04:00"

// Convert to user TZ (for display)
TimezoneDetector::toUserTimezone($model->created_at);                    // Carbon
TimezoneDetector::toUserTimezone('2025-06-15 14:00:00', 'M d, Y h:i A'); // "Jun 15, 2025 10:00 AM"
TimezoneDetector::forDisplay($model->created_at);                        // formatted string
TimezoneDetector::diffForHumans($model->created_at);                     // "2 hours ago"

// Convert to system TZ (for storage)
TimezoneDetector::toSystemTimezone($request->starts_at);   // Carbon in UTC
TimezoneDetector::forStorage($request->input('event_time')); // alias
TimezoneDetector::fromUserInput('06/15/2025 10:00 AM', 'm/d/Y h:i A'); // parse + convert

// Between any two TZs
TimezoneDetector::convertTimezone($datetime, 'UTC', 'Asia/Tokyo', 'H:i');

// Current time
TimezoneDetector::userNow();    // Carbon in user TZ
TimezoneDetector::systemNow();  // Carbon in system TZ
```

### Helper Functions

[](#helper-functions)

```
user_timezone();                                        // "America/New_York"
system_timezone();                                      // "UTC"
to_user_timezone($model->created_at, 'M d, Y h:i A');  // formatted in user TZ
to_system_timezone($userInput);                         // Carbon in UTC
convert_timezone($datetime, 'UTC', 'Asia/Tokyo');       // between any TZs
user_now();                                             // Carbon in user TZ
format_user_datetime($model->created_at);               // display string
diff_for_humans_user($model->created_at);               // "2 hours ago"
```

### Carbon Macros

[](#carbon-macros)

```
$date->toUserTimezone();                       // Carbon in user TZ
$date->toSystemTimezone();                     // Carbon in system TZ
$date->formatInUserTimezone('M d, Y h:i A');   // formatted string
$date->diffForHumansInUserTimezone();          // "2 hours ago"

// Chaining with Eloquent
$model->created_at->toUserTimezone()->format('H:i');
$model->deadline->toUserTimezone()->isPast();
```

### Eloquent Model Trait

[](#eloquent-model-trait)

```
use EslamRedaDiv\TimezoneDetector\Concerns\InteractsWithTimezone;

class Event extends Model
{
    use InteractsWithTimezone;
    protected $casts = ['starts_at' => 'datetime', 'ends_at' => 'datetime'];
}

$event->toUserTimezone('starts_at');                          // Carbon in user TZ
$event->getDatetimeForUser('starts_at', 'd/m/Y H:i');        // formatted string
$event->setDatetimeFromUser('starts_at', $input);             // converts to UTC and sets
$event->diffForHumansInUserTimezone('starts_at');             // "in 3 days"
$event->convertAttributeTimezone('starts_at', 'Asia/Tokyo');  // any TZ
```

### Blade Views

[](#blade-views)

```
{{ to_user_timezone($post->created_at, 'M d, Y h:i A') }}
{{ $post->created_at->formatInUserTimezone('M d, Y h:i A') }}
{{ diff_for_humans_user($post->published_at) }}
Your timezone: {{ user_timezone() }}
```

### Controllers

[](#controllers)

```
// Store: convert user input → UTC
$event->starts_at = TimezoneDetector::toSystemTimezone($request->starts_at);

// Display: convert UTC → user TZ
$display = TimezoneDetector::forDisplay($event->starts_at);
```

### API Resources

[](#api-resources)

```
'starts_at_local' => TimezoneDetector::toUserTimezone($this->starts_at)?->toISOString(),
'starts_at_display' => TimezoneDetector::forDisplay($this->starts_at),
```

### Queued Jobs

[](#queued-jobs)

> The session is unavailable in jobs. Pass the timezone explicitly:

```
$userTz = user_timezone();
SendReminder::dispatch($event, $userTz);

// In the job:
$localTime = convert_timezone($this->event->starts_at, system_timezone(), $this->userTimezone, 'M d, Y h:i A');
```

Using Outside Filament Panels
-----------------------------

[](#using-outside-filament-panels)

Register the middleware manually and include the JS:

```
// bootstrap/app.php (Laravel 11+)
use EslamRedaDiv\TimezoneDetector\Http\Middleware\DetectUserTimezone;

->withMiddleware(function (Middleware $middleware) {
    $middleware->web(append: [DetectUserTimezone::class]);
})
```

```
{{-- Option 1: Use FilamentAsset (recommended, no publishing needed) --}}

{{-- Option 2: Publish and use from public/ --}}

```

For option 2, publish first: `php artisan filament:assets`

Configuration
-------------

[](#configuration)

```
// config/timezone-detector.php
return [
    'system_timezone'       => config('app.timezone', 'UTC'),
    'fallback_timezone'     => config('app.timezone', 'UTC'),
    'header_name'           => env('TIMEZONE_DETECTOR_HEADER', 'X-Timezone'),
    'cookie_name'           => env('TIMEZONE_DETECTOR_COOKIE', 'user_timezone'),
    'session_key'           => env('TIMEZONE_DETECTOR_SESSION_KEY', 'user_timezone'),
    'query_param'           => env('TIMEZONE_DETECTOR_QUERY_PARAM', 'timezone'),
    'auto_middleware'        => env('TIMEZONE_DETECTOR_AUTO_MIDDLEWARE', true),
    'register_carbon_macros' => env('TIMEZONE_DETECTOR_CARBON_MACROS', true),
    'register_column_macros' => env('TIMEZONE_DETECTOR_COLUMN_MACROS', true),
    'register_field_macros'  => env('TIMEZONE_DETECTOR_FIELD_MACROS', true),
];
```

---

[](#faq)

**Q: UTC shows on first page load?**Expected — JS hasn't run yet. After the first request, the real timezone is detected and used for all subsequent requests. The `fallback_timezone` config covers this initial load.

**Q: Works with Filament SPA mode / `wire:navigate`?**Yes. The JS listens to `livewire:navigate` and `livewire:navigated` events and injects `X-Timezone` via `Livewire.interceptRequest()`, fetch/XHR interceptors, and cookies.

**Q: Works outside Filament panels?**Yes. See [Using Outside Filament Panels](#using-outside-filament-panels).

**Q: Timezone in queued jobs?**The session is unavailable in jobs. Pass it explicitly when dispatching. See [Queued Jobs](#queued-jobs).

**Q: Does this change PHP's global timezone?**No. It never calls `date_default_timezone_set()`. Only converts individual values when you call the conversion methods.

**Q: Livewire v4 compatible?**Yes. The JS uses `Livewire.interceptRequest()` (the new v4 API) with a fallback to `Livewire.hook('request')` for backward compatibility.
