DateTimeRule class

Allows you to organize the date-time values in a source data column into buckets based on selected parts of their date or time values.

For example, consider a pivot table showing sales transactions by date: +----------+--------------+ | Date | SUM of Sales | +----------+--------------+ | 1/1/2017 | $621.14 | | 2/3/2017 | $708.84 | | 5/8/2017 | $326.84 | ... +----------+--------------+ Applying a date-time group rule with a DateTimeRuleType of YEAR_MONTH results in the following pivot table. +--------------+--------------+ | Grouped Date | SUM of Sales | +--------------+--------------+ | 2017-Jan | $53,731.78 | | 2017-Feb | $83,475.32 | | 2017-Mar | $94,385.05 | ... +--------------+--------------+
