CISC-ND-001040 - The Cisco router must record time stamps for audit records that meet a granularity of one second for a minimum degree of precision.
Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records. Time stamps generated by the application include date and time. Granularity of time measurements refers to the degree of synchronization between information system clocks and reference clocks.
Configure the Cisco router to record time stamps that meet a granularity of one second as shown in the example below. RP/0/0/CPU0:R3(config)#service timestamps log datetime localtime
