@rick287: Let me ask you this.... The fact that a guy is telling you that this issue has something to do with "Bluetooth" doesn't indicate to you that perhaps he has no idea what he is talking about? Calendar synchronization over the internet with Google, Exchange, Etc. does not have anything to do with Bluetooth. Did this guy give you any explanation if...since he knows for certain this is due to "Bluetooth and Google needing to catch up to iOS 8" why users that don't use either of those things (I don't sync my calendar using Bluetooth or any Google services...I use Exchange) are experiencing the same bug?
To answer your question...yes I know differently. My Exchange host, AppRiver has 100% confirmed this bug is generated by iOS 8. They did this looking at raw server data and testing multiple equipment and account configurations. Here's an article about it: http://blog.appriver.com/2014/12/ios-8-calendar-events-display-dual-time-zones/ . Also, we have written confirmation from Enterprise and Engineering technical support at Apple that they too have confirmed this is a bug in iOS 8.
It is pretty much common knowledge that it takes Herculean effort to get Apple to acknowledge when there is a problem with any of their software or products. It seems like their employees are trained that step one dealing with any customer problem is to blame any other services or software used by the customer and to assure the customer that this can't possibly be an Apple generated issue. I swear, if you are standing in an elevator with only one other person, and that other person is an Apple employee, and all of a sudden it starts to stink in there, they will assure you that it is YOU who passed gas....
