37a33f8fbdSAdrien Destugues
38a33f8fbdSAdrien Destugues	The constructor only allows you to construct a timezone if you already
39a33f8fbdSAdrien Destugues	know its code. If you don't know the code, you can instead go through the
40a33f8fbdSAdrien Destugues	BCountry class which can enumerate all timezones in a country, or use the
41a33f8fbdSAdrien Destugues	BLocaleRoster, which knows the timezone selected by the user.
