Steps to Reproduce

Schedule an agent to run at 12:00:00 midnight.

Root Cause

It happens when an agent is scheduled to run at 12:00:00 midnight; if it ends up being scheduled to run even a second prior to that, it would be the previous day in regards to the agent timezone that results in negative value in time calculation (Next Execution Time - Current Time).

Delay of 18 seconds is the actual run time of the agent in this case.


It can be resolved by changing the scheduled start time from the top of the hour to 5 minute after the hour, that is, 12:05:00 AM EST (America/New_York). This would ensure that the agent would always be running on the same day.
