Constant PHONE_NOTICE_KEPT 

pub(crate) const PHONE_NOTICE_KEPT: i64 = _; // 21_600i64

A phone’s notice stays in the shade this long after it comes at most, then goes (the work’s at the turn of the day, 05:00, if sooner; the night’s at waking): its press carries its day, and opens nothing once the day turned (view).
