The M and Co: Five O'Clock is designed to make life easier for all the clockwatchers in your office. Allow them to focus on the one number they're actually interested in.
Of course, the real deluxe version would allow you to configure the time that you cared about depending on your work schedule.. I'm there there are plenty of employees out there on flexi time who'd like to be able to sit and stare at a slightly different set of numbers. Still, for the majority, this will be pretty cool.
