<p>By default, the node is triggered manually by clicking on its button within the editor. It can also be set to
inject at regular intervals or according to a schedule.</p>
<p>It can also be configured to inject once each time the flows are started.</p>
<p>The maximum <i>Interval</i> that can be specified is about 596 hours / 24 days. However if you are looking at intervals
greater than one day you should consider using a scheduler node that can cope with power outages and restarts.</p>
<p><b>Note</b>: The <i>"Interval between times"</i> and <i>"at a specific time"</i> options use the standard cron system.
This means that 20 minutes will be at the next hour, 20 minutes past and 40 minutes past - not in 20 minutes time.
If you want every 20 minutes from now - use the <i>"interval"</i> option.</p>
