Hap I believe that all files should be backed up routinely. After all, even if a program continually works properly, there is a good chance, particularly when a file is regularly tinkered with, you might make a mistake which you want to quickly undue. Given the tens of thousands of lines in computer code a given program has -- plus the vagueries of operating systems and pcs -- it amazes me just how many things function most of the time. If I had to guess the issue regarding RAV not always synching itself to changes in time zone changes, I am guessing that a good part of the explanation lies somewhere in how the program interacts with the pc clock. Today's decisions tell tomorrow' stories.
