- * Name: clock_time2ticks
- *
- * Description:
- *   Convert a timespec delay to system timer ticks.  This function is suitable
- *   for calculating relative time delays and does not depend on the other
- *   clock_* logic.
- *
- * Parameters:
- *   reltime - Convert this relative time to system clock ticks.
- *   ticks - Return the converted number of ticks here.
- *
- * Return Value:
- *   Always returns OK
- *
- * Assumptions:
