The time for tournament registering to open given in words has different values in the tournament listing and in the tabs. E.g. the main list says '5 minutes until registering opens' but the same tournament in the viewed tab says '6 minutes'. The time given in the tab is some 30 sec behind.
I have seen this several times. I did not follow it after the registering was open. I have the latest client, updated just some days ago. I'll post picture later.
