# daily at 01:00 - upgrade IPS rules
0 1 * * *  sh /sbin/fw_upgrade
# daily at 00:00 - sync clock
0 0 * * * /usr/sbin/ntpclient -s -p 123 -h 0.us.pool.ntp.org || /etc/init.d/ntpclient restart


There is no right or wrong......If you want fw_upgrade to run at 1am once a day and the clock to sync every midnight then leave it alone
