Why is tz_ptr templated on time_zone_type? Isn't a specific base class required from time_zone_type?
local_date_time does have a polymorphic base for time zone so that at runtime you can use posix_time_zone, custom_time_zone, interchangeably. However, didn't seem necessary to depend on a specific time zone type or even a base class in this code -- hence the template. Jeff
