[Interest] QDateTime::fromString does not work with Qt::RFC2822Date

[Alexander Dyagilev]

Thanks for the response!


Well, I don't really know if it conforms to the standard or not, but 
this "GMT" string is used by web servers (at least some of them). It's 
parsed with no issues using JavaScript.


We use QDateTime::toString to parse HTTP responses. Our users are 
complaining it's not working anymore, that's why I had to create this 
report..
