When I issue a "show logging" command to see the locally buffered logs, the log statements are displayed sometimes with an asterisk in front of the date and sometimes with a period in front of the date and sometimes with neither (see below).
000046: *Apr 22 13:05:46.064 MDT: %DUAL-5-NBRCHANGE: EIGRP-IPv4 666: Neighbor 10.1.2.3(Serial0/0/0:0) is up: new adjacency
000068: .Jul 17 08:16:52.399 MDT: %DUAL-5-NBRCHANGE: EIGRP-IPv4 666: Neighbor 10.1.2.3 (Serial0/0/0:0) is down: interface down
000083: Jul 17 09:40:41.060 MDT: %DUAL-5-NBRCHANGE: EIGRP-IPv4 666: Neighbor 10.1.2.3(Serial0/0/0:0) is up: new adjacency
What do these symbols mean?
