I also wonder how a time crystal is different from a harmonic oscillator.

  Harmonic oscillator can have a ground state where it doesn’t move (i.e. you can stop it if you remove the enegy). Time crystals move at the ground state - you cannot stop them by removing the energy.

    You actually can't remove all the energy from a quantum harmonic oscillator, 1/2 hbar omega will be in it even in the ground state.
