I upgraded to iOS 5.1 and the latest Zeo app. The times are not accurate (in my case, in CST, they are 2 hours earlier than they should be: the time zone is defaulted to PST)? Worse (in my view) is that I have two data sets for March 7th when one was actually recorded on the 8th. Last night (March 9th) the data was recorded as having occurred on March 8th. Thanks in advance for addressing these time and date issues!
