One of the things that it can do (unless you turn it off) is to give you little pop-up messages telling you what it is up to. On a Mac this is done via the Growl notification system which I then have pushed to my iPhone. Today I received a notification from Zumodrive that it had updated six files in the list “40 years 3 months 24 days 9 hours 37 minutes”.
There are a couple of impressive things about this: 1. that it can remember that far back, long before the invention of PCs and 2. that they even bothered to code for it!
However, I somewhat suspect that this is nothing more than an amusing bug.
