My two cents.  It would be better if this were flagged with an alert  
to the user to suggest they turn on time zones. An event at 2:00 PM  
PST and an event at 2:00 PM EST do not happen at the same time.   
Showing them in the same slot and doing nothing else is a very bad idea.

This could happen if the user is subscribing to a calendar in which  
events are being entered with different associated time zones.

Maybe a published calendar should have a "suggested" time zone which  
is used in just this case - when the user hasn't set a time zone view  
and there are event sin more than time zone.

Maybe this is gilding the lily, but then I fall back to saying the  
user should at least be alerted.
