How can I get current time?

[lyrics]

Hi, all. I'm using nrf52833.

I'd like to use rtc to get the current time.
What I'm trying to do is take the current time and show the time value on the LCD (year, month, day, hour, minute, second) by spi communication.

First of all, I understood to operate the built-in rtc crystal.
Then, how can I get information about time?
Is there any driver that can bring the current time from Nordic?

And after taking the time, is it right to count the time using rtc?

BR,

Hello lyrics,

As @awneil already has mentioned; this has been discussed a number of times in the forum already, and I highly recommend reading through some of these discussions for more information about this implementation.
You might also find it useful to have a look at the Current Time example from the SDK which demonstrates how to implement and use the current time service to retrieve the current time from a connected central. You will have to implement the Current Time Service on your central device for this to work.

Best regards,
Karl
