Official season end time?

Ladder Season Two Launch Timing:

North America October 6, 5:00 p.m. PDT
Europe October 7, 2:00 a.m. CEST
Asia October 7, 9:00 a.m. KST

Ladder season 1 should end exactly 1 second before ladder season 2 starts. Quoting a post from PezRadar:

"Season 1 to Season 2 will happen fairly immediately. We expect S2 to start a week or two after 2.5 hits so we have a date that everyone is aligned on and knows about. S1 will literally end the second we transition to S2.

For example: Season 1 will go to 4:59:59pm Pacific Time and Season 2 will begin at 5:00:00pm Pacific Time."
