[Boost-users] serialization of boost::local_time::tz_database

Hi everybody I just started to use boost in some of my applications. I started to serialize my objects. Now I want to serialize my boost::local_time::tz_database object, but the compiler says, there is now serialize function for this object. So do I have to add this function in the header file, or is there any other way to solve this problem. Thanks Michael
