Just a sec!

The atomic clock learned us the exact time we live in. (Unless you remember time is a matter or relativity of course...). Now every year we must turn back the clock for one second. Yes, that is one precious little second, a beautiful moment in time of no more, and certainly no less, than one full second. If we do not turn back the clock we will not be living in the right time any longer. 
Who cares... humans are outdated anyway. Highest time for the evolution of a new species. Even if your expected lifetime will be be 90 years, it means 90 x 1 second = 1,30 minutes will be lost in your lifetime. 
I hope you can live with that.
