GetPossibleInstantsFor:
5.b.i. Let _numResults_ be _list_'s length.
ii. If _numResults_ > 1, then
1. Let _epochNs_ be a new empty List.
2. For each value _instant_ in list, do
a. Append _instant_.[[EpochNanoseconds]] to the end of the List _epochNs_.
3. Let _min_ be the least element of the List _epochNs_.
4. Let _max_ be the greatest element of the List _epochNs_.
5. If abs(ℝ(_max_ - _min_)) > nsPerDay, throw a *RangeError* exception.
