activityTime property
Timestamp of the activity.
If activities for a visit cross midnight and occur in two separate dates, then two sessions (one per date) share the session identifier. For example, say session ID 113472 has activity within 2019-08-20, and session ID 243742 has activity within 2019-08-25 and 2019-08-26. Session ID 113472 is one session, and session ID 243742 is two sessions.
