    You need to manage this by software. There is only one counter in RTC.

    You set the RTC by GMT time and display the local time by adding +/- T (time offset) for each time zone.

    Which STM32?

    What do you mean by 6 different times? Do you want to display simultaneously time in 6 different timezones, like time in Tokyo, Kuala Lumpur, Los Angeles, New York, London, Kyiv, at the same moment?
