I'm trying to serialize a ptime to an xml archive. I've included boost/date_time/posix_time/time_serialize.hpp but get an ambiguity error:

[C++ Error] serialization.hpp(121): E2015 Ambiguity between 'boost::serialization::void serialize<boost::archive::xml_iarchive>(boost::archive::xml_iarchive &,boost::posix_time::ptime &,const unsigned int)' and 'boost::serialization::void serialize<boost::archive::xml_iarchive, boost::posix_time::ptime>(boost::archive::xml_iarchive &, boost::posix_time::ptime &,const unsigned int)'

Is this a problem with the compiler or should this work?

Well I suspect it is a compiler issue -- it certainly works on other compilers such as gcc. We didn't turn on the serialization regression tests for date-time during the 1.32 push so unfortunately I don't have an accurate accounting of all the compiler status w.r.t date-time serialization. Jeff
