Idle Agent Shutdown Delay
Specify the number of minutes that an elastic agent must be idle before Bamboo shuts down the elastic instance running that agent.
Elastic instances running in the Amazon EC2 compute cloud are charged in hourly blocks from the time they are started. To maximize usage of elastic instances in a cost-effective manner, Bamboo only performs these checks just prior to the expiry of each hourly block.
Here it's mentioned instances running in Amazon EC2 charged hourly, but recently all Linux ec2 instances are being charged on a Seconds basis. So the above-mentioned statement still holds?
