Steps to reproduce:

1. Create an All Day event which is not today or tomorrow
2. Open the Invite Attendees interface

Actual results:

On the display grid, there is a time difference of one hour.

Expected results:

This seems to be due to the timezone.

In the event listener load on the window object in calendar-event-dialog-attendees, there is a management of the days to display.

// Choose the days to display. We always display at least 5 days, more if
// the window is large enough. If the event is in the past, use the day of
// the event as the first day. If it's today, tomorrow, or the next day,
// use today as the first day, otherwise show two days before the event
// (and therefore also two days after it).

However, if the date is modified by going under one of the 2 conditions, this causes the bug of the one hour shift.

It would be necessary to recover startTime in the timezone of cal.dtz.defaultTimezone.
