There have been a few threads that discussed this problem. The following steps resolved it FOR ME - your mileage may vary, but I suspect this should work for you also.
1) Along the menu bar, you'll see navigation options, such as "Home", "Forum", "Classifieds", "FAQ", etc. At the far right of this bar, you will see "IRC" and "Quick Links". Click on "Quick Links", then "Edit Options".
2) In your Edit Options page, scroll down the page to the "Date & Time Options". There is a correction option for Daylight Savings Time (DST Option). By default, it is usually set to "Automatically Detect", and apparently, it sucks hard at being able to detect automatically. Change this option to "DST Correction Always On".
You should be able to log into ASC without issues anymore.
Note: if the quick link method doesn't get you to your options page, then try going to your private messages screen and accessing the options by way of the left navigation bar.
