If you're unlucky enough to live in one of the regions — like most of the United States and Canada — where spring means pushing the clocks forward an hour in what's called Daylight Saving Time but is better thought of as Lose an Hour of Sleep Night, then it's time once again to do just that. And because the iPhone and iPad have historically had as much trouble handling the change as we humans, you might want to make sure you give yourself a backup alarm backup for the evening and double-check your iOS time against some other source as soon as you wake up.
Once you're certain you'll be waking up when you're supposed to — or sleeping an hour later than normal! — let me know what you think about the idea of Daylight Saving Time in general? Personally I want to kill it with fire.
