Exchange Data Showing To Be One Day Off in Pocket Informant
We have actually been able to isolate this particular issue to a bug in iOS 7/8. The issue specifically affects Reminders that were created/edited using APIs that Apple provides to developers and then having those Reminders synced through Exchange (if you sync through iCloud, the issue does not occur and Reminders created via Apple’s Reminders app don’t experience this issue either).
To demonstrate the problem, we made a small sample project/app that reproduces the issue and we sent that up to Apple. Apple confirmed that they could reproduce the problem on their side and they are now tracking it as an issue to fix in a future iOS update. We don’t have any information from them yet on which release they plan to fix this in. Additionally, we have asked Apple if there is a suitable workaround for us to use in the interim and it doesn’t appear that there is one.
