/**
 * How the SFTP browser writes a modification date — the `sftpDateFormat`
 * setting.
 *
 * `locale` is what the panel always did: whatever Tabby's language says, which
 * is day-first in French or Spanish, `8.10.2026` in German and month-first in
 * English. The other two are fixed shapes for anyone who wants the same date
 * whatever the language (issue #11). Both are written by hand rather than
 * through `Intl` with a forced locale: no locale is guaranteed to keep its
 * current punctuation, and a shape that is the whole point of the setting
 * should not depend on one.
 *
 * Local time throughout, like `toLocaleString()` — the listing shows the time
 * of the machine reading it, never UTC.
