It is already serializable - include  
boost/date_time/gregorian/greg_serialize.hpp

In fact it is an example of non-intrusive serialization (uses only  
public interface) so you could've done this yourself, so yes it is  
possible.

However it _also_ serves as a warning.. the serialization is slow...  
much slower than would be possible with intrusive serialization which  
knows about the internal representation.

So to conclude, you picked a good example!
