Thanks for the prompt reply. 

This was from version 1.29 that I downloaded from Boost.org. 

I have been playing with the pieces of the date_time library I need 
(the line below, on the other hand, was from one of the date_time 
examples) and so far everything seems to be working without my doing 
anything unusual or different. So this is good.

BTW are you suggesting the CVS version is more up to date?
