using RTC time for time keeping

[lyrics]

Hello. I would like to use an internal RTC to keep time going even if the power is off.

1. Is it possible to implement with 'nrf_calendar' module?

2. Should I think about adding 'nrf_calendar' to the 'rtc example' to implement that function?

3. What example code would you like to refer to implement that function?

Hi,

use an internal RTC to keep time going even if the power is off.

 That is not possible. In System OFF mode, the system’s core functionality is powered down and all ongoing tasks are terminated, i.e. the internal clocks will not run.
