Timezone Settings for created_at and Similar Fields in Laravel
Managing time zones is a crucial aspect of any global application. In Laravel, setting the correct time zone for created_at, updated_at, and similar timestamp fields ensures that your application’s date and time data is accurate and meaningful. Let’s explore how to handle time zones effectively in Laravel.
Understanding Time Zones in Laravel
Definition and Significance of Time Zones
A time zone is a region of the globe that observes a uniform standard time. Handling time zones correctly in your application ensures that users across different regions see accurate date and time information.
How Laravel Handles Time Zones
Laravel uses the PHP DateTime class and the Carbon library to manage time zones. By default, timestamps are stored in UTC and converted as needed.
Configuring Time Zones in Laravel
Setting the Default Time Zone in the Config File
You can set the default time zone for your application in the config/app.php file:
'timezone' => 'UTC',
Replace 'UTC' with your desired time zone, such as 'Kolkatta/Aisa'.

Adjusting Time Zones at Runtime
You can change the time zone at runtime using the Carbon library:
use Carbon\Carbon;
$now = Carbon::now('America/New_York');

How Laravel Manages These Fields by Default
By default, Laravel’s created_at and updated_at fields are managed automatically and stored in UTC. This approach ensures consistency and simplifies time zone conversions.
Customizing Time Zone Settings for These Fields
If you need to customize the time zone for these fields, you can use the Carbon library to convert the time before storing or displaying it.
