I need to monitor for unscheduled downtime while avoiding scheduled downtime that happens at unequal hour boundary.
Detecting downtime is easy (look for no heartbeat events in last 60s).
Setting crontab to start running the searches on equal hour boundary (say, 01:00) is easy.
However, it seems to be impossible to set crontab to start at unequal hour boundary (say, 00:40).
Is there another way to implement such search?
