The Conference has agreed in principle to the proposal of the Soviet Government concerning the ultimate transfer to the Soviet Union of the City of Koenigsberg and the area adjacent to it as described above subject to expert examination of the actual frontier.
Russia annexed the area on 17 October 1945, and integrated into the republic of Russia on 7 April 1946. Poland had no role to play in this matter. Regarding time regime, I would assume that the transition from 2:00 to 1:00 of 18 Nov 1945, for occupied Germany, did not happen in Kaliningrad. It was already annexed. It remained at 2:00 until 7 April 1946, when it was integrated and went to Moscow time. This transition on 7 April 1946 is also found in Shanks. Shanks does not have the double DST from 24 May to 24 September 1945, but I think he is wrong there.

As I understand it, when a city fell to the Soviets the commander of the unit that took the city was put in charge and got to determine its clocks. If my understanding is correct, it's possible that the commander of Königsberg (later Kaliningrad) decided to synchronize with occupied Poland (or with some other region) rather than with the rest of occupied Germany. Since the USSR was planning to annex the area anyway I doubt whether the Soviets cared about keeping it in sync with the rest of occupied Germany. It'd be helpful to know who got put in charge of Königsberg/Kaliningrad during that turbulent period, and what clock-related regulations they issued. It might be hard to find that out, though.
