Calculation of Average Time on Site

[deepakkv]

If a browser tab is open and not in view whether the time will be used  calculating Average Time on Site ? If yes will it capture infinitely or whether it has a limit when it will expire ?

The time is calculated between the first and the last hit (server call) sent to Analytics.

• Append variable name to the classification based dimensions in the left rail of Analysis Workspace
• Display Info icon on dimensions in the Segment Builder Definition area
• Line Visualization Setting: Display only dimension items in Legend
• Manage Projects: Search Reports by 'Shared with'

Thank you @ Andrey_Osadchuk. My Question is when will the last hit happen. When a user comes to my site , with out further interaction he closed his browser. in this case how the last hit happen ?

Adobe Analytics needs at least two image requests in a visit to calculate time spent. Time spent will continue to count event when a tab is in the background, *only if* the user comes back to the tab with 30 minutes and causes another image request. 

Another way to think about this is, the last page/hit of a visit will not have time spend information.
