[Timer]
# Check from a minute after boot — the service needs a moment to come up, and a
# wall has its own relaunch loop — and then every minute. The jitter keeps a
# fleet of these from all waking up on the same second.
OnBootSec=1min
OnUnitActiveSec=1min
RandomizedDelaySec=5s
AccuracySec=1s
# If the host was suspended or the timer missed its window, run once anyway.
