The file attached is for DNS, not DHCP.

Events are timed when they come in to SEC, not when they come in to the log
file.  If you spawn a dump of the log file which contains 1 entry per hour
for 24 hours; SEC will see 24 events come in immediately.  It cannot parse
the log file for the time the event came in.

If you include your DHCP sec.cfg, we might be better able to help.
