Dropdown Field

If you want to use the dropdown field you can simply add a timezone to your db
fields:

<?php
use Spekulatius\TimeZones\Model\FieldType\TimeZone;
use Spekulatius\TimeZones\Forms\TimeZoneField;

class MyPage extends Page
{
    /**
     * @var array
     */
    private static $db = array(
        'UserTimeZone' => TimeZone::class
    );

    /**
     * @return FieldList
     */
    public function getCMSFields()
    {
        $fields = parent::getCMSFields();

        // ...

        $fields->addFieldToTab(
            'Root.Main',
            TimeZoneField::create(
                'TimeZone',
                'My time zone'
            )
        );

        return $fields;
    }
}

Format of time zone

You can change the default format of the time zone in the dropdown menu by
creating a file mysite/_config/timezone.yml and adding e.g.

SilverStripe\Core\Injector\Injector:
  Spekulatius\TimeZones\Model\TimeZoneData:
    properties:
      format: '%Name (%Region)'

You can use 'Name', 'Region' and 'Identifier' in the string and it will be
replaced proper.
