Usage Guidelines
Time stamps can be added to either debugging or syslog messages independently. The
uptime
keyword adds
time stamps in the format hhhh:mm:ss, indicating the elapsed time in hours:minutes:seconds since the
networking device last rebooted. The
datetime
keyword adds time stamps in the format mmm dd hh:mm:ss,
indicating the date and time according to the system clock. If the system clock has not been set, the date and
time are preceded by an asterisk (*), which indicates that the date and time have not been set and should be
verified.
The
no
form of the
service timestamps
command causes messages to be time-stamped in the default format.
Entering the
service timestamps
form of this command without any keywords or arguments is equivalent to
issuing the
service timestamps debug uptime
form of this command.
