Certain time zones have not transitions and therefore no local start time. The following spec for TZInfoTimezone tests that all TZInfo timezone identifiers can be used, and (except for "UTC") will generate a VTIMEZONE component with at least one period.

TZInfo::Timezone.all_identifiers.each do |tz|

context "TZInfo timezone #{tz}" do
  before(:each) do
    @calendar = RiCal.Calendar do |cal|
      cal.event do |event|
        event.description = "test"
        event.dtstart = "TZID=#{tz}:20090530T123000"
        event.dtend =   "TZID=#{tz}:20090530T123001"
      end
    end
  end
  it "should be allowed as a tzid" do
    lambda {@calendar.export}.should_not raise_error
  end
  unless tz == "UTC"
    it "should produce at least one period in the VTIMEZONE" do
      @calendar.export.should match(/BEGIN:(STANDARD|DAYLIGHT)/)
    end
  end
end

end
