useing timer as a counter

Question

hi, i am getting a lot of help in here, thanks a lot 
 i'm using SDK 6.0.0 for my project. and i want to use timer as a counter like as the title. 
 then, i fount the app_timer_cnt_get which can get current RTC1 value. 
 but there are some problems. 
 i get RTC1 value from app_timer_cnt_get at starting point of 1sec timer interrupt and get RTC1 value at ending point of 1sec timer interrupt. the value is 32768ticks. 
 i know that the RTC is very fast timer but, ticks from it is just 32768 druing 1sec.... 
 is it right?? actually, i need over than 100000 ticks during 1sec.

The RTC timer uses the 32.768kHz clock (sometimes references as the 32kHz clock), so with prescaler 0 it will only count 32768 times per second. I would suggest reading the RTC chapter (19) in the Reference Manua l to get a more thorough understanding of the RTC. 
 Also be aware that app_timer will clear the timer sometimes, so if app_timer_cnt_get() is called two consecutive times the second value may be lower than the first.
