I am running ossec 2.6 on Centos 5.3. I schedule a integrity check on 
servers every 8pm everyday.
We made a change on the /etc/passwd on May. But the ossec report the change 
on July.

** Alert 1374147215.4305437: - ossec,syscheck,
2013 Jul 18 20:33:35 (abc) 172.31.157.26->syscheck
Rule: 550 (level 7) -> 'Integrity checksum changed.'
Integrity checksum changed for: '/etc/passwd'
Size changed from '1885' to '1886'
Old md5sum was: '4f44d2ed0aece41fec18ead89ebab384'
New md5sum is : 'f50f15e9a541d1d60a9cdec6a0bc6ac4'
Old sha1sum was: 'af29f7247b968a6c5dadf8673cd7b57854ba2604'
New sha1sum is : '42e00da4da20e3ced4340401ad072757c8bfbc6d'

The log seems fine every day on the server, and the ossec server was 
restarted at 1:00 am every day, so the server was not reached around 1:00.
