iOS has frequently had a hard time with daylight saving time and it looks like this year is no different. This time the Calendar app is displaying the incorrect current time, which could cause some problems with your scheduling.
When you’re in the Calendar on a date after November 3 (which is when daylight saving kicks in for the US), the current time is shown one hour ahead of what it actually is. So, as the screenshot above shows, 9:20 is actually in the 10:20 slot on the calendar. It’s not the worst bug in the world — the previous alarm bug undoubtedly ruined more days and other time-based apps are unaffected — but if you rely on the calendar to plan your schedule it could be a bit confusing. Currently there’s no fix for it and mixed reports on what happens outside US time zones, so keep a close eye on your calendar this Sunday to make sure you’re actually on schedule.
Memo to Apple: this happens twice a year. Should not be that hard to get it right.
