Does it contain anything for the converse - converting from a
SysTime to "Sat, 6 Jan 1990 12:14:19 -0800"?
If not, should it?
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.

I needed it for the If-Modified-Since HTTP header, through
std.net.curl.HTTP.addRequestHeader.
Phobos has HTTP support and this is the preferred date format
according to spec. Phobos should support it.
