## Why it's here

Surfaced by the search "SQLite last_accessed column unix timestamp vs datetime performance indexing" as a directly on-topic forum thread (integer vs. other types for a timestamp column); not opened or quoted independently during this pass beyond what's already captured in the Tier 1 dossier for the primary SQLite forum source.
