Due to eal_alarm_callback() and rte_eal_alarm_set() use gettimeofday() to get the current time, and gettimeofday() is affected by jumps. For example, set up a rte_alarm which will be triggerd next second ( current time + 1 second) by rte_eal_alarm_set(). And the callback function of this rte_alarm sets up another rte_alarm which will be triggered next second (current time + 2 second). Once we change the system time when the callback function is triggered, it is possible that rte alarm functionalities work out of expectation. Replace gettimeofday() with clock_gettime(CLOCK_MONOTONIC_RAW, &now) could avoid this phenomenon.
