If the - keyword is not used, system messages are displayed from the beginning of the buffer. If number_of_messages is not specified, the last 20 messages in the buffer are displayed.
If the logging timestamp option is enabled, a timestamp is also included in the display. Use the set logging timestamp command to enable the timestamp option.
If the logging timestamp option is enabled, the +00:00 or -00:00 in the output indicates the hours and minutes offset from UTC.
This example shows how to display all the system messages from the internal buffer; this example displays the output with the timestamp option enabled:
