    while (--i >= 0) {
        char ch = dateStr.charAt(i);
        if (ch < '0' || ch > '9') {
            // 07-Aug-2013, tatu: And [databind#267] points out that negative numbers should also work
            if (i > 0 || ch != '-') {
                break;
            }
        }
    }
    if ((i < 0)
        // let's just assume negative numbers are fine (can't be RFC-1123 anyway); check length for positive
            && (dateStr.charAt(0) == '-' || NumberInput.inLongRange(dateStr, false))) {
        return _parseDateFromLong(dateStr, pos);
    }
    // Otherwise, fall back to using RFC 1123. NOTE: call will NOT throw, just returns `null`
    return parseAsRFC1123(dateStr, pos);
