How does RTC compensate for daylight saving?

NNada.1

Hello All,

  I came across the daylight saving feature in RTC peripheral of STM32F401RE. I live in a country where there is no concept of daylight saving, hence this is new to me as well. As per the RM of STM32F401RE, there is a automatic daylight saving correction in RTC peripheral.

  1. How does the MCU correct the time for daylight saving ? My assumption is that it waits for specific date and there it would increment the current time. 

 Can anyone please provide more insights, about how is daylight saving feature working in STM32F401RE or some reference.

Thank you,

Regards,
