After the recent time change (EST to EDT), the FreePBX machine is one hour ahead. Here’s some output from various tools:
[root@~ log]# zdump -v /etc/localtime |grep 2009

I tried stopping NTPD, running ntpdate pool.ntp.org, hwclock -systohc, and then starting NTPD. This seems to fix it for the day until around 2am when the clock jumps ahead an hour.
I’m not sure what I can do from here. I haven’t rebooted the machine yet, it’s been up for around 23 days or so, and I haven’t checked the BIOS clock. I find it odd that it keeps resetting every night.
Neither FreePBX nor Asterisk do anything to change the system time, and your time change settings (zdump) seem correct, and you didn’t say anything about your area not observing DST, so I’m wondering if either your system thinks you are in a different time zone than what you really are, or you have encountered some weird operating system bug that might be fixed by doing an update of the OS. I know something’s wrong because the output of your date command is showing Thu Mar 19 09:24:30 EDT 2009 which is still about two minutes in the future as I type this reply!
Wondering if you found a resolution to this. Obviously that link is pretty old now and is dead.
I am having the same problems with AsteriskNow - which is CentOS and FreePBX. The time shown for Time Groups is an hour ahead of the operating system time. OS time is set by NTP, which is working, and the time zone afaik is set to Australia/Brisbane. It’s as if FreePBX has it’s own TZ settings, and is set to Sydney (which is on DST, an hour ahead of the Brisbane TZ).
Not having any luck finding a resolution to this. As far as I’ve found, there isn’t anywhere in CentOS that specifies DST or not, and as mentioned, it doesn’t seem to be configured for a DST TZ.
