Does daylight saving change MSK to JST?
Moscow Time does not move its clocks at all, so its UTC+3 offset holds every day of the year.
Japan Standard Time does not move its clocks at all, so its UTC+9 offset holds every day of the year.
Is MSK ahead of or behind JST?
MSK is behind JST by 6 hours: when it is 12:00 pm in Moscow, it is 6:00 pm in Japan. Neither Moscow Time nor Japan Standard Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Moscow Time covers Moscow and western Russia, fixed since 2014. Japan Standard Time covers Tokyo, Osaka and the whole of Japan. The identifiers behind them are Europe/Moscow and Asia/Tokyo, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
