The sysklogd script invokes the
syslogd program with
the -m 0 option. This option
turns off the periodic timestamp mark that syslogd writes to the log files
every 20 minutes by default. If you want to turn on this periodic
timestamp mark, create or edit /etc/sysconfig/init_params and define the variable
SYSKLOGD_PARMS to the desired value. For instance, to remove all
parameters, set the variable to a null value:
SYSKLOGD_PARMS=
See man syslogd for
more options.
