Thx -- that's helpful.

Don't know, but having this show up on the boost list can't hurt.

I don't have a copy of VC8, but your test and explanation is enough.

I've checked changes into CVS that remove all the use of basic_stringstream in
date_time that should impact VC8 (there's some usage for legacy compilers that
isn't easy to remove that's still there).  Those interested in patching should
be able to pick up these files their boost tree:

date_time/format_date_parser.hpp 1.10
date_time/strings_from_facet.hpp 1.4
date_time/time_zone_base.hpp     1.6
date_time/time_facet.hpp         1.19

Thx for the help Sean.
