Last time I checked, boost has one.

He probably means that long long is not part of the (official) standard, although most compilers do support long long.

Well not really. Some compilers call it long long -- some call it other names. That's why there is boost::int64_t (and friends) which mirrors the C types from stdint.h. I can assure you that it works on every platform where date-time compiles b/c I use it for the internal representations and it works just fine. The documentation of this is a bit hard to see, but if you read about exact-width integers at: http://www.boost.org/libs/integer/cstdint.htm you'll find it. So the practical effect is that it's there if you want it. Also, I believe the library working group is considering adding these C types for TR2 -- so eventually it will be official... Jeff
