getcreationtime on Flowitem

Of course my question has to do with LABELS since I've watched every FlexSim video on earth and labels are the bain my existence these days. I want to set a label on all my flowitems to getcreationtime and to getexittime (is this a command, because I couldn't find it on the command menu). Where do I do this and where can I compare the answers?

Basically, it is very important that every flowitem is processed in less than 1440 time units total. I need to track this information I can not figure out how to do it. Any suggestions? I've attached my model for reference.

Hi betabethany,
I remember sometime back i saw a thread some thing related to this.Hope this can help you

and there is a model in download section Sample_TimeLabelQueueSorting_TD

The items have a time stamp which are the creation date.

Every flowitem has the attribute “stats_creationtime”. To get this time use the commandgetcreationtime(). To calculate the flow time or time in system just use time() minus getcreationtime().

In your model I would use the OnEntry trigger of the sink “Sk-ToShipping. To store the information for all flow items you could use a global table or a node (e.g.label) with bundle data.
You could popup a screen message or write into the Output Console if the time is greater1440.
