No, it does not contain the reverse. It was added specifically for the installer. If it weren't for that, std.datetime wouldn't support it at all. It's a horrible format that should just die. The only reason to use it is because the e-mail spec (and thus specs like HTTP) unfortunately uses it. However, anyone that's going to need to generate the format for anything like that is going to need a lot more than that that Phobos doesn't provide anyway, so I really don't think that it's much of a loss. Regardless, I'm strongly of the opinion that anything dealing with that format should be restricted to a library for e-mail or HTTP, and if it weren't for the fact that the installer needed to be able to read it (I forget why), I would have argued strongly against adding parseRFC822DateTime to Phobos. - Jonathan M Davis
