Where Is the nrf_drv_timer.c Files in 15.2 SDK

[rraa]

I couldn't find nrf_drv_timer.c file. I want to create timer so I try to different SDK for my work. I am using SEGGER IDE for prepare software but i encountered lots of problems. First i used Keil ide than i changed my mind. I am using SEGGER. But i am suprised about SDK 15.2 because i did not find nrf_drv_timer file. I guess change sdk again. I have to use SDK 15.0.

Where have you seen that file mentioned?

Have you looked at the SDK examples for how to use a timer?
