I suspect the Google Calendar user interface may be contrary to your
intuition.  The selector for time zone only lists the standard time
offset from GMT, without regard to DST status.

A quick test suggests that the correct time is used for events.  An
event with start time in my local zone (US EST) and end time in NZ
time has the correct duration.
