No timestamp when a track was favorited (Favorite tracks)?

[mrdc]

Hello,

I'm checking Yandex.Music API and it looks like they don't store a timestamp when I favorited a track (Favorite tracks playlist).
But at the same time I see the timestamp in All tracks playlist: in mobile apps tracks are divided: Yesterday, This Week, Last Week, Junuary etc. Or there is a possibility to retrieve timestamps?
