I think what the user meant is the leaderboard reset time.
If it does, the leaderboard reset time is every 00:00 UTC. Just convert it to your respective timezone.
Thanks for explain, when I took at this picture below, yes, reset time 00.00 UTC.
It's temporary either, every time I refresh the leaderboard, the number and rank would be change.
I made an experience using rollbit on my phone, looks great and going smooth on my chrome browser. I didn't yet any browser like firefox or others, if you have used it, I want to know how your experience..
