pub fn cutoff_for(days: u32, now: DateTime<Utc>) -> DateTime<Utc>Expand description
The started_at cutoff for a days-day retention policy evaluated at now: runs
started at or before this instant are in scope for deletion. Pulled out of
sweep_retention so commands::history::prune’s --dry-run preview can compute and
display the exact same cutoff its non-dry-run sibling would actually delete against,
without needing a database handle to do it.
