June 8, 2020 (23:59:59 GMT): submission system closes
I am writing this post on 3rd June, ~10pm in Warsaw, which is in GMT+2 zone, so we have ~5d4h left (2h added because of GMT+2). The timer on the site displays that we have 4 days, 2 hours from now.
Please specify which date is the true date of the closing of the submission system (I believe the schedule is correct) and fix the schedule/timer according to the one that displays the correct information.
