From the viewpoint of quantum physics, the Planck constant is a mere conventional quantity used to set a unit to the concept of energy which is defined as a measure of frequency. This constant seems mysterious as long as you keep the classical view which defines energy as an a priori quantity. But as soon as you give up the classical view of energy as an independent quantity, and you accept to redefine it as a measure of frequency, then you are entering the understaning of quantum physics.
We can make a comparison with the sound which splits into harmonics. Every vibrating object of finite size makes a sound with a precise list of harmonics (of a finite number of frequencies lower than any given value), the same as any object of finite size can only have a finite number of energy levels lower than a given value.
But frequencies in a system with an unknown form of perturbation, cannot be accurately measured if the sound is only recorded in a limited period of time, no matter the means.
Sorry what do you mean by your question ? what do you mean by "break this "energy-time"?" what "quantum jump" are you talking about ? I hardly know anything about string theory but I guess it does not change anything to the nature of Planck's constant.
