• Interesting fact: Daylight savings time started during World War I, so Americans could use as much natural lighting as possible and conserve energy needed for war production. Despite the Uniform Time Act, which Congress passed in 1966 to standardize the time change, several states within the United States do not observe Daylight Saving Time. They are Arizona, Hawaii, parts of Indiana, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa.

On account of Noether’s theorem which associates a conserved dynamical quantity to each generator of a symmetry of a dynamics, relativistic ﬁelds evolving within a Minkowski spacetime with its invariance properties under spacetime translations and rotations also possess conserved energy, momentum and angular-momentum.
A Pedestrian Introduction to the Mathematical Concepts of Quantum Physics
In the same manner as for the energy, we shall understand later on how conservation of momentum is related to invariance of the system under constant translations in space, and conservation of angular-momentum to invariance under constant rotations in space.
A Pedestrian Introduction to the Mathematical Concepts of Quantum Physics
Consequently, the linear momentum is conserved only if the particle is free, ~F = ~0, while the angularmomentum may be conserved even in the presence of a nonvanishing force provided only it is radial, namely always colinear with the position vector ~r .
A Pedestrian Introduction to the Mathematical Concepts of Quantum Physics
However, when the time evolution parameter coincides with the physical time, the above conservation law shows that in direct correspondence with the invariance of a dynamics under arbitrary time translations its total energy is a conserved quantity, namely the Noether charge generating that symmetry.

These conserved quantities are also the generators of these symmetries on phase space through the Poisson brackets of these conserved quantities with any phase space observable, beginning with the phase space coordinates.

Then, in general, the orbit of the classical motion samples completely the hypersurface of the phase space that corresponds to all conﬁgurations which respect the conservation of certain extensive conserved quantities; then the system is called ergodic 1 and thermalization is expected.
