elapsed time in nanoseconds

Dear Freescale team,

 

in section 3.9.3.4 of MQXUG you say that I can get elapsed time in ns by calling _time_get_elapsed, followed by _time_get_nanoseconds.

 

The _time_get_elapsed gives something like 10 seconds, 756 milliseconds, right? Does the _time_get_nanoseconds then count the remaining ns ? It says 'ns since last periodic timer interrupt', when was this interrupt in our case?

 

Thanks for your help.

Heinz
