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?

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.
