Another daylight savings switchover, another bug on iOS. Fortunately, it looks like Apple has finally gotten rid of the serious bugs, such as issues with the alarm, and this bug is merely a visual problem. You might not even notice it. To the left, you can see the bug. The time is 2:36 PM, but the red line appears to be drawn at 1:36 PM.
Apple has had an issue with daylight savings time every year since 2010. While this little bug is mearly an annoyance to those which an incessant need for perfection (aka: the kind of people who like Apple products), Apple will most likely have a fix for this bug soon.
