# Task Timers

**Attached Events** are added to the **BPMTimerEventMonitor** collection when it's parent task is created. And it is removed from **BPMTimerEventMonitor** collection when the task is finalized.

**Timer Events** are added to **BPMTimerEventMonitor** collection when a *token/transition* arrive to the event. And it is removed from **BPMTimerEventMonitor** collection when answer \[true] to any **Monitor** evaluation.

**Timer Block** are activiated by ***Blocks***. In each evaluation ***aBlock*** always answer **true** or **false**. **Blocks** receive three parameters when the evaluation is done: 1) ***lastExecutedTime*** - \[aTimeStamp] with the last executed time. 2) ***currentTimeStamp*** - \[aTimeStamp] which is the current time. 3) ***process*** - \[aBpmProcessInstance] which is the Bpm Process itself.

The **Attached Timer Block** in this case is executed each 10 seconds.

The **Timer Event Block** in this case will wait X seconds before resuming the execution of the process. X is defined by the **BpmProcess** variable \[***termValue***]. This variable was set in the previous task of the **BpmProcess**.
