The time designated in the highlighted column below is not related to the time specified in a policy:
CloudHealth goes through all policies and checks to see if the policy should fire every 15 minutes. If the time matches up with the evaluation time specified in the policy block, the policy will fire. If the time does not, the policy will not fire.
Be advised the evaluation time will still update on that policy page. The best way to understand this column is that is presents the last time CloudHealth evaluated whether or not we should evaluate the policy, NOT if it was actually triggered.
