-To change the system time and date, enter the <code>datetime {format}</code>. The format must be 'yyyy-mm-dd hh24:mi:ss'. Note that if you manually change the system time and date while the NTP is enabled, you encounter the "Failed to set time: Automatic time synchronization is enabled" error. Therefore you need to disable the NTP before configuring the system time and date manually.

-You can specify the order of logs display. This configuration affects when if you execute the <code>show log</code> command without -w option. you can verify current setting by executing <code>show system logsort</code>. If the sort is "desc," it shows logs in descending order. If the sort is "asc", it shows logs in ascending order.
