If existingDate is earlier than date, the range covered by
generated entries must cover at least from existingDate (excluded)
to date (included). If existingDate is later than date,
the range covered by generated entries must cover at least from date
(included) to existingDate (excluded).
The generated entries may cover a range larger than the minimum specified above
if the generator prefers to generate large chunks of data at once. It may
generate again entries already generated by an earlier call (typically at existingDate), these extra entries will be silently ignored by the cache.
Non-coverage of the minimum range may lead to a loss of data, as the gap will
not be filled by the GenericTimeStampedCache in subsequent calls.
The generated entries must be chronologically sorted.
