Timestring is the pattern used for matching the dates in indices and snapshots.
You can construct date strings using
strftime formatting. While it is often used in conjunction with the
--time-unit flag, a timestring pattern can be used to merely match indices
with that pattern, rather than to filter by date, as with --older-than or
