A Better How Long is a freeware utility program that lets you know in real time how much time was elapsed since the computer was booted up. ABHL lets you customize the font color and size and then you can leave the little floating window anywhere on your screen and know precisely since how much time the Mac is up. It also has the option to save the boot log to a text file.
