For me all dates are really messed up. Year is wrong and day and month also does not match(see attachment)
Only my times are messed up. Ex: says posted at, say 2:00 AM, when in reality, my time, it was posted 12:00 PM. Not years, just times of posting.
Is your account set to the right time zone? Not sure if the app automatically detects and changes it because it seems to just be a web view.
