''' SF_Region
''' =========
''' Singleton class implementing the "ScriptForge.Region" service
''' Implemented as a usual Basic module
'''
''' A collection of functions about languages, countries and timezones
''' - Locales
''' - Currencies
''' - Numbers and dates formatting
''' - Calendars
''' - Timezones conversions
''' - Numbers transformed to text
'''
''' Definitions:
''' Locale or Region
''' A combination of a language (2 or 3 lower case characters) and a country (2 upper case characters)
''' Most properties and methods require a locale as argument.
''' Some of them accept either the complete locale or only the language or country parts.
''' When absent, the considered locale is the locale used in the LibreOffice user interface.
''' (see the SF_Platform.OfficeLocale property)
''' Timezone
''' Specified as "Region/City" name like "Europe/Berlin", or a custom time zone ID such as "UTC" or "GMT-8:00".
''' The time offset between the timezone and the Greenwich Meridian Time (GMT) is expressed in minutes.
''' The Daylight Saving Time (DST) is an additional offset.
''' Both offsets can be positive or negative.
''' More info on
''' https://timezonedb.com/time-zones
''' https://en.wikipedia.org/wiki/Time_zone
'''
''' Service invocation example:
''' Dim regio As Object
''' Set regio = CreateScriptService("Region")
