Description

Ripper algorithm recognizes timestamp features (e.g. 2022-06-14-19.39.35.929641) as integers, and thus encodes them to categorical features. The resulting rules are in terms of equality predicates (e.g. timestamp == 2022-06-14-19.39.35.929641) instead of intervals/inequalities as one would expect.

Proper timestamp type support for Ripper would be nice.

Research direction

Start by locating the Ripper algorithm entry point and tracing how timestamp features are recognized and encoded. Confirm the current equality-based rules, then define completion as timestamp features producing interval or inequality predicates instead; add or run focused coverage for the reported timestamp example.
