Clear app_timer counter

[corentind]

Hello,

I am using an app_timer on my nRF52840 (SDK 15, Softdevice 140) to keep track of the time on my device.
After a specific event, I would like to be able to clear the counter of the timer. I have tried stopping the timer and starting it again but it does not seem to reset the 24-bit counter.
I have also tried to use the app_schedule as mentioned in this post without success.
How can I reset the timer?

Thanks

Thank you. Why shouldn't the COUNTER of the RTC be reset? 

I posted the wrong link in my question. The post I was talking about is here. It seems like there is a way to reload the value?

There is no problem resetting a RTC counter in general. However, from your question it seems this is the same RTC as is used by the app_timer (RTC1). And in that case, resetting the RTC will cause the app_timer to lose track of time.
