When I create an event in one these same calendars in Outlook, it shows up on the iPhone at the right time, so I am thinking it is Outlook not Apple.Its also more noticeable if you use Outlook for Windows with two time zones enabled and the default zone is west of the secondary zone. When I create an event on my iPhone it shows on my Outlook calendars, which are iCloud based, one hour ahead. Verify that the time zone settings are correct and that they are the same as the settings in the Windows Date and Time control panel.I saw this post on an Apple forum researching my problem - it is exactly my issue and the time it has been a problem and the location (Perth, WA) are the same for me - HELP. Click the Time Zone button. In Outlook 2010/2013/2016 go to File > Options > Calendar. In the Time Zone section, make sure that the time zone and Daylight Savings Time settings are correct for your region.

All my appointments that I have sceduled in my iphone calendar in Icloud appear in Outlook 1 hour later eg 7:00pm in Icloud is showing 8:00pm in Outlooks Icloud Calendar, Also in the personal calender of Outlook. Make sure that the checkbox for time zone is selected.'I am running Outlook 2013 & only using the Icloud calendar in Outlook. Scroll down to the bottom of the list of apps and services, then click the Details button next to System Services. From the Privacy pane, select Enable Location Services.

As much as I don't need to look on my computer as much as my Iphone 5S, I want it to match. My time on my computer is correct & we have no daylight saving in Perth Western Australia. My calender settings in Outlook is correct.
