Create event in iCloud calendar for different time zone How do I create a future event in a different time zone than I'm currently on?

For example, I reside in Toronto (UTC-5) and I am going to Hong Kong (UTC+8). When I'm still in Toronto, I want to be able to create an event (in Hong Kong time) so that when I arrive in Hong Kong, the event appears correctly in the local time.
I am assuming that you are using the website for this.  Go to iCloud, and open the Calendar app.  Click on the gear at the top-left, then click preferences.  Go to the advanced tab, and check "Enable time zone support".  Now, when you edit an event, you can select the time zone in the event information.
