That's great to have it, but I had it already implemented in my private branch. But my solution checked if the json value can be converted to a date using IsDateString function:

bool IsDateString(const String& s)
{
	if(s.GetLength() != 10)
		return false;
	
	int cnt = 0;
	for(int i = 0; i < s.GetLength(); i++) {
		if(IsAlpha(s[i]) || IsSpace(s[i]))
			return false;
		if(!IsDigit(s[i]))
			 ++cnt;
	}
	return cnt == 2;
}

and then in ParseJSON I changed if(p.IsString()) section to:

if(p.IsString())
{
	String s = p.ReadString();
	if(IsDateString(s)) {
		Date d = ScanDate(s);
		if(!IsNull(d))
			return d;
	}
	return s;
}

The good thing is it does accept most of the date formats that satisfy ScanDate function.
However relaying on unofficial standard might be better.
