How to use mutators in hasMany laravel?

Question

Laravel

Hello!
Got a question. There are 2 models, A and B . Model A is related to model B via hasMany .
Model B contains a date format field, as well as a mutator

protected $dates = [
      'time'
    ];

However, when fetching through a relation, the mutator is not applied to the given attribute and I get a bare string.
I also tried to make a crutch by writing a getTimeAttribute getter to model B , which would explicitly create a Carbon date from a string, which also did not work, because the attribute is not called) Surely there is a way to cope with this task simply and elegantly. Can you advise?)
