Version 1.4. is out to the App Store and we’ve received several complaints about the weird bug that appears when setting the time for classes: instead of AM the app’s showing PM time or time shifts all the time depending on your location.
We’ve taken a close look to the issue and it appeared that in iOS 4 the time zone support is not working the same way it used to in iOS 3.1.2. It is not what you call a nice surprise, but we can deal with it.

We assume doing this way will fix the issue.
Meanwhile we’are submiting a quick fix to the App Store.
ALSO, the fix will solve the problem for those who use iPhone 3G and experience crashes after the update. Crashes are caused by local push notifications option which eats more memory (but save your traffic actually).
