Bundle Status

Can someone please explain to me how long it should take for the bundle deployment status to get uploaded to the server? For example, once the DAU bundle runs, how long should it take to report to the server that it is completed? I can see a zipped file in the following client location but I need to know when I should expect this to upload to the server:

C:\Program Files\Novell\ZENworks\work\zmd\status

Thanks
