CoreS3 RTC

[mr-vaezi]

Describe the bug

Hello,
Hope you are doing well,

I have an question regrading to RTC example included for CoreS3.

would you please let me know that in this Example, ESP32's internal RTC was used or BM8563's RTC,

because i have tested it over a day, and it is 4 Seconds behind NTP.

I would be tankful if you let me know, because i just want to know that if BM8563 has a bad performance or what?

To reproduce

i added nothing to the file. i just loaded it on the board.

Expected behavior

I expected that does not fall behind the NTP this fast.
