Recurrency by DateAndTime correct displayed in Dayview but wrong redirect in Singleview.
Error: In dayview the events are listed correctly but when you click on a event it always redirects to the latest time in singleview. (See "Reproduce")
Create a new event with a start and end date, time is set to 12:00 (shouldnt matter what time really). Go to the "Recurrence" Tab. (NOT a All Day Event)
Activate "Date and Time" in Dropdown-Menu.
Enter some values (can be on the same day, but be sure they dont have the exact same time. (eg. 30.06.2013 at 12:00. and 30.06.2013 at 19:00)
Now visit the Frontent page for that day (30.06 in the example above) and click the earliest of your events. You will see that you will get redirected to the event with the latest time. (Expected: 30.06.2013 19:00; Result: 30.06.2013 12:00)
Version cal = 1.5.3
Version TYPO3 = 4.5.25
