Dear RNT
I would like to get ESP32 cam to work on weekly basis. I have two ways to do this

  1. ask NTP server. Disadventage 

 – if internet connection somehow fail, ESP32 CAM will not work properly as well.  
 – Wfi is battery consuming operation
      2. RTC module :DS1307, DS3231
 which pin do I use for esp32 cam i2c?

It depends on which board you have as to what pins are available.

Hi.
I haven’t experimented with the ESP32-CAM and an RTC module.
Are you using the microSD card? You may find useful taking a look at the ESP32-CAM pinout: https://randomnerdtutorials.com/esp32-cam-ai-thinker-pinout/
