Plugins - TZInfo Timezone
Add to favoritesThis plugin installs a replacement for the TimeZone class. The replacement uses the TZInfo library (http://tzinfo.rubyforge.org) to do the time zone conversions, and thus takes into account daylight saving, for free.
It is not a 100%-compatible replacement, however. If you use TimeZone#unadjust anywhere, you'll need to replace those calls, possibly with #local_to_utc. Also, the #adjust method is deprecated--it is better (and easier to read) if you use the #utc_to_local method instead.
Note that you will need to have the tzinfo library installed separately--it is not bundled with this plugin. You can easily install tzinfo as a gem:
gem install tzinfo
Andrew: It may be due to you using composedof on the timezone. Composedof seems to freeze
Try changing the tzinfo of tzinfo_timezone.rb method to
def tzinfo MAPPING[@name] = TZInfo::Timezone.get(MAPPING[@name]) if String === MAPPING[@name] return MAPPING[@name] end
thus avoiding the frozen @tzinfo.
Used it at own risk, but works for me at least.
You can also check our extension of TZInfo, which lets you do the following in models for auto conversion:
hastimezone :fields => [:startdatetime, :end_datetime]

This plugin really improves life for i18n apps. But, many developers have been using TZInfo "manually" for some time and have invested in attributes (on User or Account, etc.) to track the TZInfo timezone by name. Furthermore, some find the TZInfo zone names to be more intuitive.
It would be great if this plugin would accept the TZInfo timezone names as well. I offer my patched version. See http://cho.hapgoods.com/wordpress/?p=140
