// clock.js a clock that update only when it's really required and what is required.
// What i mean with this is that for exemplo at the time 10:11:00 the clock just update the seconds and the minutes, not que hours.
// the close doesn't update at a fixed time like almost every clocks, just update when the output is different form the actual output
