symbolic timezones don't work with tzinfo

#28

The documentation implies that including tzinfo will allow time zones like "America/New_York" to function. However, this simple test script explodes when trying to access the date field.

!/usr/bin/ruby

require "pp"
require "rubygems"
require "tzinfo"
require "ri_cal"
require "open-uri"

open("http://mhvlug.org/calendar/ical") do |file|

@@cal = RiCal.parse(file)

end

pp @@cal.first.events.last.dtstart

The exception is as follows:

/var/lib/gems/1.8/gems/ri_cal-0.8.5/lib/ri_cal/component/calendar.rb:155:in find_timezone': "America/New_York" is not the identifier of a VTIMEZONE component of this calendar (RiCal::InvalidTimezoneIdentifier)

    • State changed from new to invalid

    RiCal only uses TZInfo to create calendars.

    The ical file provided is invalid because contrary to RFC 2445 it does not contain VTIMEZONE components sufficient to resolve all (actually in this case any) of the times with timezones within the file.

    This is a bug in whatever software produced that file. (The drupal calendar api according to the product id), not in RiCal.

    Ok, I misread the documentation, and thought ri_cal supported this. I'll continue to use icalendar.rb then as it works fine with the drupal ical feeds.
