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-.
