Ticketmaster showing when pre-season home games occur

Ticketmaster seems to be showing the Blackhawks' pre-season home schedule before it has been announced this year. Looking at their Hawks page, it shows the following home games:

September 23rd vs. Blue Jackets - 7:30 PM CST
September 26th vs. Wild - 7:30 PM CST
September 28th vs. Stars - 6:00 PM CST
October 5th vs. Avalanche - no time listed

The last one confuses me, however. A pre-season game as late as October 5th? Usually the regular season begins around the 3rd or 4th on most seasons, I'm trying to remember a pre-season game as late as then but not coming up with anything. Perhaps that is the home opener? Only time will tell.
