How to work with time zones in Carbon for PHP?

Working with time zones in Carbon for PHP is quite straightforward. Here are the steps:

1. Install Carbon: First, you need to install Carbon in your PHP project. You can either use Composer or download the Carbon package directly from the GitHub repository.

   composer require nesbot/carbon

2. Import Carbon: After installation, import the Carbon class at the top of your PHP file:

   use Carbon\Carbon;

3. Set the default timezone: Set the default timezone for your Carbon instance. You can use the timezone method to set the desired timezone. For example, to set the timezone to UTC:

   Carbon::setTimeZone('UTC');

4. Create a Carbon instance: You can create a new Carbon instance using the now method, which returns the current date and time in the default timezone:

   $now = Carbon::now();

5. Convert to a specific timezone: You can convert a Carbon instance to a specific timezone using the tz method. Pass the desired timezone as a parameter to the method. For example, to convert $now to the 'America/New_York' timezone:

   $nyTime = $now->tz('America/New_York');

6. Display the converted time: You can display the converted time using the format method. Pass the desired format as a parameter to the method. For example, to display the converted time in the 'Y-m-d H:i:s' format:

   echo $nyTime->format('Y-m-d H:i:s');

7. Perform timezone calculations: Carbon provides various methods to perform timezone calculations. For example, if you want to add or subtract hours from a Carbon instance, you can use the addHours or subHours method:

   $newTime = $nyTime->addHours(2); // Add 2 hours

   You can also perform calculations with other units like minutes, days, months, etc.

That's it! You now know how to work with time zones in Carbon for PHP.
