    Use a bit more standard null date in lcl_normalizeDateTime
    
    This value is only used for dates comparison inside ODateTimeType;
    _getValue is used in OValueLimitedType_Base::_validate to comnpare
    to minimal and maximal cached values, and the latter are set using
    normalizeValue. The choice of null date is ~random, and in theory,
    we could just normalize using Date::GetAsNormalizedDays(), but the
    null date close enough to the actual dates has an upside of keepng
    enough precision for time part - so just use the most used epoch,
    which gives an optimized GetAsNormalizedDays, and hence, a faster
    operator-.
