Today's 1PM tourney began at 2PM DST. Official clock said 2PM but tourney countdown was at 1PM. Sent an e-mail to CS but have not heard. Not sure if this another version of the DST bug, in which case I guess all will be well in 3 weeks or so. In the meantime, just be careful when you plan your playing
They seem to have fixed it. The tournament details page still shows the tournament as being an extra hour away, but the 4, 5, 6 and 7:00 all started at the right time.
The time countdown inside the tournament lobby is an hour off. The scheduled times are accurate otherwise.
