# OnUnitActiveSec alone has no base until the service has run once in this boot, and an
# already-elapsed OnBootSec is not re-armed for a timer started later — a timer enabled
# after boot then shows NextElapseUSecMonotonic=infinity and never fires. OnActiveSec is
# based on the timer's own activation, so every start arms the chain.
