Best practices: Where should I assign value to an EF model DateTime property

Hello, I would need to assign DateTime.UtcNow to a property called CreatedAt. Should this be done in the model, business logic layer or repository layer?

c#
public class Entity
{
    public long Id { get; set; }
    public DateTime CreatedAt { get; set; }
}

c#
public class Entity
{
    public long Id { get; set; }
    public DateTime CreatedAt { get; set; }
}

.HasDefaultValueSql("getdate()") Or whatever the function for getting the date is in the database you use
