A conserved quantity means that it does not change with time. Time itself changes with time at a rate of 1 second per second, so it is not conserved.

Time is not conserved.

ds^2 = [(p_x)^2 + (p_y)^2 + (p_z)^2 - (p_t)^2]; metric signature (+1,+1,+1,-1), Relativity

ds^2 = [(p_t)^2 - (p_x)^2 - (p_y)^2 - (p_z)^2]; metric signature (+1,-1,-1,-1), field theory

(same thing) are locally conserved.
