What we do know is this – you will be able to tune in to the Spring Forward event live, as live streaming is available today beginning at 10am PST. If you intend to tune in to the live streaming event, it would be prudent to know that you will need an iOS device or a machine that runs on OS X – and even then, not any iOS-powered device will do, as you will also need to ensure that Safari 5.1.10 or higher on OS X v10.6.8 or later are installed, and mobile users, Safari on iOS 6.0 or later would be the prerequisite. Apple TV owners, streaming the event would mean you will have to have a 2nd or 3rd generation unit, complete software 6.2 or newer.
