track time

[james]

I want to use a timer to track time. Like having a variable that shows minutes/seconds/ms/etc. But I don't know how to do with that.I want to use the rtc, but rtc1 had been used by app_timer and the rtc0 will be affected by Timer0,1,2.

Create your own app timer that uses rtc1 and keeps running so you can keep track of the current time.
