Not sure if this is a Mongoid or Rails bug, but I have an "Event" object that has a Time field

When I try and store
"Sat Jan 12 2013 14:00:00 GMT-0500 (Eastern Standard Time)"

What's stored into Mongo (from the console)
"Sat, 12 Jan 2013 14:00:00 UTC +00:00"

So you can see it should either be
Sat, 12 Jan 2013 19:00:00 UTC +00:00
or
Sat, 12 Jan 2013 09:00:00 EST -05:00

I've tried in my applicaiton.rb:
config.time_zone = 'Eastern Time (US & Canada)'
config.local_zone = 'Eastern Time (US & Canada)'
Time.zone = 'Eastern Time (US & Canada)'
Mongoid::Config.use_utc = false
Mongoid::Config.use_activesupport_time_zone = true

No dice. Is this a bug in Mongoid or a bug in my settings?
