Hi,
There's a problem on HP-UX (especially hppa2.0w-hp-hpux11.11) with gcc-3.3.6, where localtime_r and gmtime_r are not in namespace std.
boost-1.33 itself is built with "<cxxflags>-pthread/<linkflags>-pthread"

Two maybe interesting notes:
1) /usr/include/time.h only declares localtime_r/gmtime_r if '-pthread' compiler-flag is used (and therefore _REENTRANT is defined).
2) gcc-shipped <ctime> does not pull localtime_r/gmtime_r into namespace std
Thanks!

c_time.hpp is the only place where localtime_r and gmtime_r are used. Neither instance is preceded by a std::. Looking back through previous versions of c_time.hpp, also shows no usage preceded by a std::. I attempted your example and am unable to duplicate your error. I would suggest you check your copy of c_time.hpp against the one found in cvs (found here) http://tinyurl.com/9jrd2 Bart
