Horde Timezone
==============

[](#horde-timezone)

Parses the [IANA timezone database](https://www.iana.org/time-zones) (Olson format) and generates iCalendar VTIMEZONE components.

Installation
------------

[](#installation)

```
composer require horde/timezone
```

Quick start
-----------

[](#quick-start)

```
use Horde\Timezone\TimezoneDatabase;
use Horde\Timezone\TimezoneDatabaseConfig;

$db = new TimezoneDatabase(new TimezoneDatabaseConfig(
    location: '/path/to/tzdata/',
));

echo $db->getZone('America/New_York')->toVtimezone();
```

The `location` parameter accepts:

- A directory path containing unpacked Olson source files
- A path to a `.tar.gz` tarball
- A URL to download (default: `ftp://ftp.iana.org/tz/tzdata-latest.tar.gz`)

Legacy API
