1168536 - Events with timezone get moved on a wrong day after a drag and drop in month view

Status: RESOLVED FIXED

(Calendar :: Calendar Frontend, defect)

Description

[Decathlon]

- Steps to reproduce:

1. set Lightning's default timezone to America/New york;
2. import the following calendar with an event in UTC/GMT timezone:

BEGIN:VCALENDAR
BEGIN:VEVENT
CREATED:20150413T125116Z
LAST-MODIFIED:20150413T125154Z
DTSTAMP:20150413T125154Z
UID:2caf0f7c-9b33-4e64-b7a9-7da46e965646
SUMMARY:Test drag&drop event with timezone
DTSTART:20150520T010000Z
DTEND:20150520T020000Z
END:VEVENT
END:VCALENDAR

3. in month/multiweek views, drag and drop the event on a different day.

- Actual result:

after the drop, the event gets moved on the earlier day than the day where the drop occurs.

The bug doesn't occur in day/multiday view.

The drop session sets the event on a day based on the item date's timezone instead of the default timezone that should be used to display the events in the views.
