 The function `get_ms_count()` can be used to read the current RTOS kernel millisecond tick count. The below code snippet demonstrates use of the `get_ms_count()` function to calculate the elapsed time:
 
-```
-void send_data()
-{
-    // 64-bit time doesn't wrap for half a billion years, at least
-    uint64_t now = Kernel::get_ms_count();
-    //do some operations

 ## Kernel hooks example
 
 You can use the function `attach_idle_hook()` to attach a function to be called by the RTOS idle task. You can use the function `attach_thread_terminate_hook()` to attach a function to be called when a thread terminates. The below code snippet demostrates the usage of these hooks.
