Data::ICal::Entry::TimeZone - Represents a time zone definition in an iCalendar file

       Best Practical Solutions, LLC <modules@bestpractical.com>

       A Data::ICal::Entry::TimeZone object represents the declaration of a time zone in an iCalendar file.
       (Note that the iCalendar RFC refers to entries as "components".)  It is a subclass of Data::ICal::Entry
       and accepts all of its methods.

       This module is not yet useful, because every time zone declaration needs to contain at least one
       "STANDARD" or "DAYLIGHT" component, and these have not yet been implemented.
