Over the weekend -- in many countries, but not the U.S. -- Daylight Saving Time ended, and clocks fell back by an hour. As reported by AppleInsider on Sunday, though, U.S. iOS 7 users can prep themselves for another DST bug.
Apparently, users who have already had DST end are seeing the time displayed incorrectly, but only inside of the platform's built-in calendar app. Users who look at the calendar's Day View, will see the bar which represents the current time appear in the appropriate position, but with a time that is one hour behind.
According to the report, the issue doesn't affect other parts of the system, such as alarms or calendar event notifications.
Apple has a history of issues with keeping time. In 2010, an iOS 4 bug caused most alarms to trigger an hour later than they should have following another Daylight Saving Time change. Meanwhile, on New Year's Day 2011, many iOS users discovered that their non-recurring alarms had been disabled overnight.
Those bugs were later fixed , so they will likely push out a patch soon. The patch might even come this week, before the DST change in the U.S. this weekend.
Meanwhile, the news will probably not distract Apple fans from the upcoming launch of the iPad Air and the iPad mini with Retina display, scheduled for Friday, Nov. 1. The iPad Air is significantly downsized and lightened from last year's iPad 4, and the iPad mini is seeing a Retina display for the first time in its lifetime.
