Adafruit feather sense Internal Clock

Hello 

I also have the adafruit feather sense board  with the nrf52840 processor and i am using zephyr to program it .The only way to work is for me to enable the  32k internal RC Oscillator by writing 

# 32kHz clock source - necessary for Adafruit Sense (Internal Clock!)
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y


I was wondering if the reason for not working is that zephyr RTOS needs the RTC .

Could you explain why the initialization  of the internal 32k clock  is necessary ?


Thanks
