 Simply including boost/date_time/posix_time headers causes build times to
 skyrocket. Building a file that includes
 boost/date_time/posix_time/posix_time.hpp takes almost a minute, removing
 the header drops the time to less than a second.
 Also why no conversions to time_t? It would be nice not to have include
 the header outside of translation units. :)

Comment(by marshall):
 Is this still a useful request?
 Here's what I got on my MacBookPro (junk is just 'main', junk2 includes
 "boost/date_time/posix_time/posix_time.hpp")

 DuoTwo:~ marshall$ time g++ -I /Marshall/Sources/boost/trunk junk.cpp

 real    0m0.056s
 user    0m0.025s
 sys     0m0.023s

 DuoTwo:~ marshall$ time g++ -I /Marshall/Sources/boost/trunk junk2.cpp

 real    0m1.641s
 user    0m1.395s
 sys     0m0.228s
