MS Outlook-compatible Timezone Definitions

iCal4j ZoneInfo Outlook provides alternate timezone definitions that may provide greater compatibility with certain versions of Microsoft Outlook. These definitions are generated using tzurl - a fork of vzic, and apparently avoid things Outlook doesn't like (such as RDATE properties).

Usage

To use the alternate timezone definitions you may create a custom TimeZoneRegistry instance using the applicable prefix:

    CalendarParser parser = CalendarParserFactory.getInstance().createParser();

    PropertyFactoryRegistry propertyFactoryRegistry = new PropertyFactoryRegistry();
    propertyFactoryRegistry.register(WrTimezone.PROPERTY_NAME, WrTimezone.FACTORY);
    propertyFactoryRegistry.register(WrCalName.PROPERTY_NAME, WrCalName.FACTORY);

    ParameterFactoryRegistry parameterFactoryRegistry = new ParameterFactoryRegistry();

    TimeZoneRegistry tzRegistry = new TimeZoneRegistryImpl("zoneinfo-outlook/");

    builder = new CalendarBuilder(parser, propertyFactoryRegistry, parameterFactoryRegistry, tzRegistry);

A convenient factory for the Outlook-compatible definitions is also provided, so in such cases all you need to do is add the following property to your ical4j.properties included in your classpath:

net.fortuna.ical4j.timezone.registry=net.fortuna.ical4j.zoneinfo.outlook.OutlookTimeZoneRegistryFactory

Minimum requirements

None.
