RTC Module

I have some questions on the RTC Module:

  1. What is the time drift of the RTC Module?

  2. How often do I need to sync the RTC Module using Network time?

  3. Does the AGX need to be synced regularly with the RTC Module, or only at startup?

  4. Does the RTC Module have an internal battery? How often does it needs replacement? How do we know if the battery needs replacement?
