The Tinsley 5646 was designed in the late 70s based on LM399 reference IC. You can expect long term stability similar to a 34401A multimeter.
The right side circuit is normally off and switched on only for calibrating the left side output which is continously powered. That reduces the drift a little but introduces a hysteresis problem.
