This morning, I created my tournaments as usual at 09:10 EDT from the website.
They all showed "Start:
in 3 hours" immediately after creation.
I then looked at the Open Tournaments page.
All of the tournaments had ENTER NOW and LEADERBOARD buttons. The start time was 02:10. It has always been like this. The time then changes to 09:10 shortly after that but people can enter the tournament immediately from the website.
I looked at the Open Tournaments page again a few minutes later.
All of them say "Start:
in 3 hours" and have a start time of 09:10. You can't enter the tournament or look at the leaderboard from the Open Tournaments page.
On the other hand, one is able to enter the tournament or look at the leaderboard from within the game itself (both the mobile and computer versions).
Update (11:26 EDT): Our Open Tournaments page is now showing "Start:
in an hour".
