When working in a Request and performing updates to the Tasks or Work Log  the "Last Update Time" is not affected by the addition of information.

When a technician is working on multiple requests and is updating a Task or WorkLog, it is helpful to know what they are working on by seeing a current time stamp associated with the request on the main view...not having to drill into the history of each technician's request.

So...what are the sets of criteria that update the "Last Update Time" ?
