This is Facebook's fault. FB has a *horrible* strategy for dealing  
with timezones in the events API.

Facebook stores the event time as if it were in Pacific Standard Time.  
i.e., I'm on the east coast of the US, I enter an event to start at  
4:00EST. They store the event as 4:00PST translated to UTC. So, when  
using the API you need to do the calculations yourself. That would be  
fine, except to do the translation properly, you need to know the  
event *creator's* timezone, which we don't know. I took a best fit  
approach, and do the translation based on the Horde user's timezone.

This works correctly on Facebook's website since they have access to  
all users' timezone information.
