NAME

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

SYNOPSIS

           my $vtimezone = Data::ICal::Entry::TimeZone->new();
           $vtimezone->add_properties(
               tzid => "US-Eastern",
               tzurl => "http://zones.stds_r_us.net/tz/US-Eastern"
           );

           $vtimezone->add_entry($daylight); # daylight/ standard not yet implemented
           $vtimezone->add_entry($standard); # :-(

           $calendar->add_entry($vtimezone);

DESCRIPTION

       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.

METHODS

   ical_entry_type
       Returns "VTIMEZONE", its iCalendar entry name.

   optional_unique_properties
       According to the iCalendar standard, the following properties may be specified at most one
       time for a time zone declaration:

               last-modified tzurl

   mandatory_unique_properties
       According to the iCalendar standard, the "tzid" property must be specified exactly one
       time in a time zone declaration.
