second
The second function you provided is similar in purpose to Carbon{:target="_blank"}'s
second method. Both are used to retrieve the second part for a given time or datetime.
Example Usage
use sbamtr\LaravelQueryEnrich\QE;
use function sbamtr\LaravelQueryEnrich\c;
$book = Book::select(
'id',
'name',
QE::second(c('published_at'))->as('published_second') // That's a weird example. But I couldn't come up with a better example! :D
)->first();
