End Timezone is ignored when creating events in a Google Calendar account

Google Calendar seems to white list Apple Calendar (or itself) when creating events with different start and end timezones. When creating an event in BusyCal that spans across different timezones for its start and end dates, Google ignores the end timezone, updates its copy and this is then overwritten when BusyCal syncs the next time.

You need to instead:

• Navigate to https://calendar.google.com
• Click on the event you wish to modify
• Click Edit Event
• Click on Time Zone
• Click Use separate start and end time zones

Making a change in Google Calendar itself will stick and sync over to BusyCal.
