Ok so now I'm an idiot. Disregard half of what I said because the basic issue that yes I can confirm that you can not change your Sites Time Zone from GMT -6. This means that scheduling for everyone is probably appearing in Central US time.
It has been so long since I looked at the Account Profile screen that I did not realize Chops had finally added a personal time zone setting There. I can validate however that since my server is in Central Time that the settings all serve the purpose intended and thus a clock probably really isn't needed. Once I set my time zone to GMT -7 it correctly shows that the raid will start at 7pm local time to me.
This will be really helpful since we have a guild member that do to her schedule is on a US Server but lives in Australia.
