Timezone location in HTTP `Date` header is unsupported

[gasinvein]

E.g. Fri, 17 Nov 2017 13:46:28 Asia/Shanghai can't be parsed and raises ValueError. And seems like there is no way to parse timezone database location name with datetime.datetime. Does anyone know a library suitable for parsing HTTP Date header?

According to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Date and other sources like https://httpwg.org/specs/rfc7231.html#header.date that header is illegal. In that format (IMF-fixdate in the language of RFC 7231) the zone field is the literal string GMT. So it may be hard to find an off-the-shelf parser for this illegal format. :-)
