AFAIK this should mostly "just happen" for those 32bit systems that have a 64bit time_t. BTW, the funny part of this discussion is that the problem has existed "for ever". It just so happens that there is now a bunch of "easy" OS-level solutions. The magical 2208988800 constant is the "standard solution" that I was looking for (I knew it had to exist because it had not OS-level solution for at least 30 years). Stefan
