dear sir

   i test 3100 rtc function with SDK release_mra2_10_1_nhs3100,i use the app_demo_dp_tlogger project with the APP NHS3100 temperature logger.

i know the procedure when use the 3100 about rtc

  1. when set config  the rtc will be set with Chip_RTC_Time_SetValue function (this value is phone time )
  2. when i get config ,i can get the rtc value from Chip_RTC_Time_GetValue function ,(this value is time running by 3100)
  3. in fact ,after running 1 day ,i get the rtc from 3100 is 2 minutes smaller than the phone time .

is there anything wrong ?why 3100 rtc is not  accurate as expect ?
