## Why it's here
|
||
|
|
|
||
|
|
Surfaced by the search "SQLite last_accessed column unix timestamp vs datetime performance indexing" as a mirror of SQLite's official date-function documentation. Its specific technical point — that an INTEGER value needs the `'unixepoch'` modifier or SQLite's date functions will misread it as a Julian day number — is recorded directly in the `sqlite-forum-timestamp-integer-vs-text.md` Tier 1 dossier, sourced from the broader search synthesis rather than an independent read of this specific mirror page. A second mirror of the same documentation (sao.ru) also surfaced and is treated as the same underlying source.
