How often does the source representative check for file changes on the source

Hi,

As stated in the LANDesk Content Replication - Source Configuration document, "The Source representative will periodically check the files on the source, determine the hash and write that information to an XML file". Does anyone know how often this is? Periodically is quite vague...

Also:

- is there a way to modify it, like a registry key or something else?

- is there a way to clear this and force a full recalculation on the source representative?

Thanks in advance,

Patrick
