WLocale::setTimeZone seems to be broken now.
Congratulations on the new release!
Wt 4.0 seems to have revised a function that is no longer backwards compatible.
void Wt::WLocale::setTimeZone(const date::time_zone *zone)
seems to reference a type "date::time_zone*" that isn't defined or described anywhere. The Wt 3 version would accept a string. Is this function still usable? If so, what is this type?
