 The `struct_time` representation is more difficult to work with, but can be sorted as-is which is the primary use-case, and can be converted relatively easily to `date` or `datetime` objects (provided the year is within 1 to 9999 AD) or to date objects in more flexible libraries like [astropy.time](http://docs.astropy.org/en/stable/time/index.html) for years outside these bounds.

-The fuzzy dates are derived from the strict dates, plus or minus a level of padding that depends on how precise the date specfication is. For the case of approximate or uncertain dates, we (arbitrarily) pad the ostensible range by 100% of the uncertain timescale, or by a 12 weeks in the case of seasons. That is, if a date is approximate at the month scale, it is padded by a month. If it is approximate at the year scale, it is padded by a year:
