I downloaded version 0.3.12 of TZInfo from [1], and observed that it  
has a very robust set of timezones including, for example, ‘America/  
Anchorage’:

irb(main):001:0\> require ‘rubygems’  
=\> false  
irb(main):002:0\> require ‘tzinfo’  
=\> true  
irb(main):003:0\> TZInfo::Timezone.get(‘America/Anchorage’)  
=\> #\<TZInfo::DataTimezone: America/Anchorage\>

Within Rails 2.2, however, which appears to have the same version of  
the gem (see the error that follows), the set of timezones is far more  
limited.

irb(main):001:0\> require ‘rubygems’  
=\> true  
irb(main):002:0\> require ‘active\_support’  
=\> true  
irb(main):003:0\> TZInfo::Timezone.get(‘America/Anchorage’)  
TZInfo::InvalidTimezoneIdentifier: no such file to load – tzinfo/  
definitions/America/Anchorage  
from /usr/local/lib/ruby/gems/gems/activesupport-2.2.2/lib/  
active\_support/vendor/tzinfo-0.3.12/tzinfo/timezone.rb:108:in `get’  
from (irb):3

Perhaps the maintainers of TZInfo didn’t bump up the version number of  
the gem after adding additional timezone data?

The bundled TZInfo is intentionally limited in size. If you have the  
full version installed,  
Rails will load that instead. See also this ticket:
