/**
* Provides support for converting dates to strings and vice-versa.
* The strings are structured so that lexicographic sorting orders by date,
* which makes them suitable for use as field values and search terms.
*
* <P>Note that this class saves dates with millisecond granularity,
* which is bad for {@link lucene::search::RangeQuery} and {@link lucene::search::PrefixQuery}, as those
* queries are expanded to a BooleanQuery with a potentially large number
* of terms when searching. Thus you might want to use
* {@link lucene::document::DateTools} instead.
*
* <P>
* Note: dates before 1970 cannot be used, and therefore cannot be
* indexed when using this class. See {@link lucene::document::DateTools} for an
* alternative without such a limitation.
*
* @deprecated If you build a new index, use {@link lucene::document::DateTools} instead.
* This class is included for use with existing indices and will be removed in a future release.
