A quick-acting AppleInsider reader has spotted a live "test" video for an event scheduled for September 10 at 1:15PM Eastern Time on Apple's YouTube channel — which has since been removed.
The video showed up in a recommended feed on YouTube which shows off current videos and future events. The video in question listed a live stream scheduled for September 10, which would align with the 2019 event by date, but not by day.
The data for the video, seen in this article sent by Ben from Nottingham, England, depicted a Thursday event at 1:15 PM Eastern Time which is highly abnormal for Apple events. The iPhone is normally announced at the beginning of the week with pre-orders that Friday or the next. Apple also starts events at the top of the hour, so take the image even more skeptically.
