When I enter a new appointment on my Windows Live calendar on my iOS device, it is shifted by an entire day forward on my WP8 and Windows Live account.

The strange thing is: the basic info displayed for the appointment (day and time) is correct e.g. 17 July, but it is displayed on the 18 July (*one day later*) in the month/week view. And when I click on "View details", the date is shifted to *one day earlier* (16 July).

How can my original entry on the iOS device for 17 July suddenly be displayed on the 18 July (and still saying "17 July" under "Start/End"), and become an appointment on the 16 July when clicking on "View details" - all this on the same Windows Live calendar?

Your advice is much appreciated.
