Duration is the period of time in minutes that the time event is 'active'. The duration field specifies the maximum number of minutes after the specified time has been reached that the dependency is kept in an active state.
When a job has multiple dependencies, use the duration field to set a window of time in which the time dependency remains active so that other dependencies can also be met.
Example: Flow A is specified to run only if a file dependency and a time dependency are both met. The time dependency has a 'Duration of event' value of 10. When the start time specified for the time dependency is reached, the flow will run if the file dependency is met at any time up to 10 minutes later.
