Enum CatchUp 

pub enum CatchUp {
    Always,
    Never,
    Within(Duration),
}

How long after a missed slot it is still worth running.

Both extremes are legitimate and neither is a safe default for the other: a nightly rumination wants to catch up whenever the machine comes back, and a 07:00 briefing delivered at 23:00 is noise. One knob, three behaviours.

Variants

Always

Run the missed slot whenever it is noticed. systemd’s Persistent=true.

Never

Only run a slot that is still fresh. A missed one is recorded as skipped and the schedule moves on.

Within(Duration)

Run a missed slot if it is younger than this.
