a domain specific custom identifier of the content of the marked interval.
This parameter can be used for marking intervals that actually started before the method call. If you do not specify it, the ExperienceSDK will use the current time as the timestamp. To shift the timestamp, set this parameter to the amount of elapsed milliseconds since the last device boot at the actual time when the interval started.
Number of seconds after which the interval will automatically be considered closed by the backend, even if no ending signal is received.
