drop thread.sleep(), use timeunit's sleep()

Everybody has a Thread.sleep() call somewhere in his code.
sleep() method only accepts milliseconds and if you need some sleep functionality with another time granularity you have either to calculate the sum of milliseconds and put a magic number in the code

Thread.sleep(86400000L);

or a more readable way to do it

Thread.sleep(1000L * 60 * 60 * 24);

or a much more readable way;

TimeUnit.DAYS.sleep(1);

More beautiful code right?
