Future timestamps in /var/log/secure

I happend upon this ( https://bugzilla.redhat.com/show_bug.cgi?id=193184 )
which seems to suggest/explain the occurrence. I know it was mentioned to be
in the CentOS distro, but I think this might have been adopted into that
distro as well since I see the same issues on a RedHat Distro. Not sure if
the article helps or hinders but good food for thought.

Isn't the timestamps inserted by syslog rather then the reporting 
program itself?

What syslog do you use - classic (ie: sysklogd) or a modern one like 
rsyslog?  It almost looks like the timezone got changed from local to 
GMT or similar, then swapped back (as odd as it may sound).

Perhaps time to file a bug report with the author of the syslog daemon 
you use?
