Cannot translate "ago" text using "time ago" in views

is there any way to translate “ago” in “time ago” date format in views.
I found and translated

%time ago
@time ago

strings but still not working

I changed the line 69 in views.install

$view->set($base . '.settings.past_format', '@interval ago');

“ago” here but nothing changed
