I think I have my timezone class ready for prime time, so I should be just about ready to finish the larger civil time library (which I put on hold because a couple of the classes depend on timezone).

But as I write this, I remember that there’s one thing I haven’t tested yet:  the option of reading TZ and TZ_ROOT environment variables using std::getenv() before the timezone class gets used for anything.  I do that magically with some tricky code that has the odor of the poltergeist anti-pattern; so I need to create the TZ and TZ_ROOT environment variables on my Windows box and make sure that that works.  I don’t see any reason why it won’t, so I’ll say tentatively that I’m done.
