# Process Creation Timer

When a **BpmProcessDefinition** has a ***timer*** in **StartEvent** then each time the ***timer*** answer \[true] then a **BpmProcessInstance** of that process has to be created.

The **OS Process** compare all process definitions that are being monitored with created process instances and evaluates the ***timer*** to created another instance or not. **Blocks** receive two parameters when the evaluation is done: 1) ***lastExecutedTime*** - \[aTimeStamp] with the last executed time. 2) ***currentTime*** - \[aTimeStamp] which is the current time. In the example below **aBpmProcessInstance** is created each day.

**Monitor** Each **BpmProcessDefinition** timer is compared with the last **BpmProcessInstance** *creationTime*.
