As I see the session log in /var/log/secure,
the time stamp for the proftpd is somehow CST(theplanet time) like below.
other services like xinetd are all loged as server time(France) as normal.

#cat /var/log/secure
...

Sep 11 04:58:25 secure xinetd[22995]
Sep 11 04:59:34 secure xinetd[22995]
Sep 10 21:59:48 secure proftpd[21733] @CST
Sep 11 04:00:45 secure xinetd[22995]:
..
..

I added `TimesGMT off` to /etc/proftpd.conf
but it didn`t fix it. (It fixed the proftpd time itself but not the session log time)

Please give me hint. How about yours anyway? Please check your ftpd session log in /var/log/secure.

My server is runnning RHE4 with ensimX.
