# Data::ICal::Entry::TimeZone(3pm)

Represents a time zone definition in an iCalendar file

## 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.
