The software clock keeps an “authoritative” flag that indicates whether the time is authoritative (believed to be accurate). If the software clock has been set by a timing source (for example, via NTP), the flag is set. If the time is not authoritative, it will be used only for display purposes. Until the clock is authoritative and the “authoritative” flag is set, the flag prevents peers from synchronizing to the software clock.

Table 91 describes the symbols that precede the timestamp.

Table 91	Timestamping Symbols for syslog Messages
Symbol	Description	Example
*	Time is not authoritative: the software clock is not	*15:29:03.158 UTC Tue Feb 25 2003:
	in sync or has never been set.
(blank)	Time is authoritative: the software clock is in sync	15:29:03.158 UTC Tue Feb 25 2003:
	or has just been set manually.
.	Time is authoritative, but NTP is not	.15:29:03.158 UTC Tue Feb 25 2003:
	synchronized: the software clock was in sync, but
	has since lost contact with all configured NTP
	servers.

The following is sample output from the show logging summary command for a Cisco 12012 router. A number in the column indicates that the syslog contains that many messages for the line card. For example, the line card in slot 9 has 1 error message, 4 warning messages, and 47 notification messages.

Note For similar log counting on other platforms, use the show logging count command.
