Timezone of time displayed differs from entered time - Sunbird Lightning Calendar

Issue: If the operating system timezone and the Calendar timezone do not agree, then after entering a time in the event dialog and clicking OK, the time displayed in the view is not the same as the time just entered.

Versions:

• Sunbird 0.3 and later
• Lightning 0.1 and later

Background:

• The date and time parsers and pickers used in the event dialog depend on the operating system timezone.
• The calendar displays use the calendar timezone.
• The developers haven't found any way to get a Windows timezone that works IN ANY LOCALE. (The standard API returns a localized string.)
• Therefore, the timezone needs to be set in two places.
• bug 300605

Workaround: Make sure the operating system timezone and the calendar timezone agree.
