Or if 1 minute intervals are acceptable you can edit the appropriate
place so that syslogd runs with option '-m 1' and then edit
/etc/syslogd.conf so that it includes the line

mark.*                          /var/log/tstamp

and then that tstamp file will contain things like 

Nov  4 11:44:04 Way -- MARK --
Nov  4 11:49:04 Way -- MARK --
Nov  4 11:54:04 Way -- MARK --

(which resulted from '-m 5')

This on a very old Linux system, from the days when you constructed
your own distribution from the available pieces.
So file locations and available options will surely have changed a
little in the interim.
