I think !parse reads better than parse == nullopt. But I suppose others might argue that the ! one looks like it’s about 0; not for me. (As an aside, I hope we change our style to allow "== 0" at some point.)

What does the word "set" refer to in this (already existing, not new to this patch) function name?

> Source/WebCore/platform/DateComponents.cpp:116
> +    const CharacterType* current = src + parseStart;
> +    const CharacterType* end = current + parseLength;

I just woulda done auto for these.

> Source/WebCore/platform/DateComponents.cpp:201
> +    return createFromString(source, [] (auto& date, const auto* src, auto length, auto& end) {

Not a big fan of the use of the string "src" here. Also I think just auto src would do, no need for const auto*.

Even though I had comments I think I will set commit-queue+, probably good to land this as-is.
