+# timers
+
+This roles manage systemd timers, to execute commands at regular interval.
+Just define the timers you want at the host, or group level, like :
+
+```
+system_timers:
+  - id: db-janitor     # Just an identifier for the task
+    calendar: '*:0/30' # See man systemd.timer for examples
+    max_duration: 1h   # Max duration of the task. Will be terminated if it takes longer
+    command: |
+      #!/bin/bash
+      psql -U postgres -d reports -w << _EOF
+        delete from audit where time < now()-'7 day'::interval;
+      _EOF
+  - id: logrotate
+    calendar: daily
+    command: logrotate -f /etc/logrotate.d/myservice.conf
+```
