I'm trying to fetch events from the user's Calendar app. That itself works fine, but one thing isn't quite right. I'm displaying the `title`, `location`, `startDate`and `endDate` in different labels. Now, my problem is that both `endDate` and `startDate` are running one hour late, so when I set an event for 19:00, it appears as 18:00 in my app. I'm using this code:

```
// Create the predicate's start and end dates.
CFGregorianDate gregorianStartDate, gregorianEndDate;
CFGregorianUnits startUnits = {0, 0, -30, 0, 0, 0};
CFGregorianUnits endUnits = {0, 0, 15, 0, 0, 0};
CFTimeZoneRef timeZone = CFTimeZoneCopySystem();

gregorianStartDate = CFAbsoluteTimeGetGregorianDate(
CFAbsoluteTimeAddGregorianUnits(CFAbsoluteTimeGetCurrent(), timeZone, startUnits),
timeZone);
gregorianStartDate.hour = 0;
gregorianStartDate.minute = 0;
gregorianStartDate.second = 0;

gregorianEndDate = CFAbsoluteTimeGetGregorianDate(
CFAbsoluteTimeAddGregorianUnits(CFAbsoluteTimeGetCurrent(), timeZone, endUnits),
timeZone);
gregorianEndDate.hour = 0;
gregorianEndDate.minute = 0;
gregorianEndDate.second = 0;

NSDate* startDate =
[NSDate     dateWithTimeIntervalSinceReferenceDate:CFGregorianDateGetAbsoluteTime(gregorianStartDate,     timeZone)];
NSDate* endDate =
[NSDate     dateWithTimeIntervalSinceReferenceDate:CFGregorianDateGetAbsoluteTime(gregorianEndDate, timeZone)];

CFRelease(timeZone);

// Create the predicate.
NSPredicate *predicate = [eventStore predicateForEventsWithStartDate:startDate     endDate:endDate calendars:nil]; // eventStore is an instance variable.

// Fetch all events that match the predicate.
NSArray *events = [eventStore eventsMatchingPredicate:predicate];

```

Does anybody have an idea how to fix this? Thanks in advance!
