Great tool! We are doing humanitarian work worldwide. We are now using BTsynch to maintain the files of the 3-4 laptops in the remote location. As a result, no data is anywhere in a Cloud. If worst comes to worst, we can grab any laptop and have all data with us. In addition, we are also synching several computers at the home base. This works so-so, but is considerable less reliable. Could this be because home base is in a different time zone? Can anyone explain (better) the "synch_max_time_diff" settings to me? We use the default of 600s. What happens if one of the laptops is off by more than this amount?
