> At present, Pattern#withIn defines the maximum time interval in which a matching pattern has to be completed in order to be considered valid. The interval corresponds to the maximum time gap between first and the last event. The maximum time gap between events is needed in the certain scenario, for example, purchases a good within a maximum of 5 minutes after browsing.
