understand-author_date

CALL NUMBER: deep_commit_object.author_date DEFINITION: Composite of author_timestamp and author_timezone; git log --date= formats this value.

Invoke this skill to understand author_date down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from deep_commit_object

• author_timestamp (d1): Integer Unix timestamp recording when the author created the change; represents seconds since epoch (1970-01-01 00:00:00 UTC) in the author field.

Projected from the git internals and the object model KB (162 concepts / 159 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.
