Research direction
Start with tests/by-util/test_date.rs around lines 3300-3304 and reproduce the reported date -d command. Trace the date parsing entry point used by the date utility and compare its behavior with the GNU example. Done means dates with a missing year and an explicit time are accepted with the expected interpretation, while the relevant test passes.
