What the hell is this I hear you ask? Well when I'm doing work where the client is paying by the hour I tend to jot down the start and end time of each block of work. This results in a list of what I was doing and the times I did it between, but then my fuddled brain has to work out exactly how long that was.
And this is where the little client side feature below comes in. Yes I got sick of using my brain to do this, I just wanted to paste in a list of stuff and times, and get hours out the other end.
