Horde Timezone

Parses the IANA timezone database (Olson format) and generates iCalendar VTIMEZONE components.

Installation

composer require horde/timezone

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)
