## Generate DateTimeImmutable objects ##

The generator generates by default DateTime objects.

The generator can generate DateTimeImmutable objets with `generateDateTimeImmutable` method:

```php
use Ecommit\FrequencyGenerator\FrequencyGenerator;

$generator = new FrequencyGenerator();

$date = $generator->nextInEveryDay([new \DateTime('10:00:00'), new \DateTime('08:00:00')]);
echo get_class($date); //This example will output "DateTime"

$generator->generateDateTimeImmutable(true);
$date = $generator->nextInEveryDay([new \DateTime('10:00:00'), new \DateTime('08:00:00')]);
echo get_class($date); //This example will output "DateTimeImmutable"

$generator->generateDateTimeImmutable(false);
$date = $generator->nextInEveryDay([new \DateTime('10:00:00'), new \DateTime('08:00:00')]);
echo get_class($date); //This example will output "DateTime"
```
