Systems and methods are provided for scheduling an automation (e.g., an automated workflow) to execute against a specified set of data (e.g., a customer support ticket) based on when time-based conditions within the automation will (or will likely) be true or satisfied with regard to the ticket. The automation's time-based conditions are represented by one or more functions designed to yield, when executed against a given ticket, a time interval during which those conditions will (or will likely) be true for that ticket. When a function produces a valid time interval, the corresponding automation is scheduled to run against the ticket during the interval. The functions may be quickly executed each time a ticket is modified (or created) because they may be created in assembly language or a native language of the computing platform that executes them.
