Generated code will be:

- (double)valueAsDate
{
    return IMPL->valueAsDate();
}

- (void)setValueAsDate:(double)newValueAsDate
{
    WebCore::ExceptionCode ec = 0;
    IMPL->setValueAsDate(newValueAsDate, ec);
    WebCore::raiseOnDOMError(ec);
}

The type should be NSAbsoluteTime, not double.

WOuld making IsPrimitiveType return true for Date give you more of the code paths you need with out $idlType eq "Date"? Or is IsPrimitiveType used other places we don't want for Date? Could those be specialcased for Date?

Seems fine though…

Darin is right, this should be NSAbsoluteTime.

[Darin Adler]

I do think this can be done without adding "Date" in so many different places. Maybe we can claim it's a primitive type.

Would you give me information about NSAbsoluteTime please?
I couldn't find it in header files and references.

Oops, sorry. It's NSTimeInterval (from NSDate.h). There should be an NSAbsoluteTime, but there is not!

But also, dates inside WebKit are in seconds from a base of 1970, whereas in AppKit they have a base of 2001. So we will need to correct by kCFAbsoluteTimeIntervalSince1970 as we do in CurrentTime.cpp.

There is CFAbsoluteTime, documented with an epoch of 2001. But I think NSTimeInterval is better to use since we are not a CF API.
