log files time zone question

[Monty]

What exact time zone are log files time stamped in? Does it ever change?
I searched and found this
https://service.futurequest.net/inde...-raw-log-files
On line 4 at that linked example, it shows the -5 which I assume is GMT -5 time or UTC Offset Standard time for Florida time. My particular log file entry looks like this however.

[Thu Jan 17 09:58:30 2019] [error] [client 93.158.161.170] client denied by server configuration: /big/dom/x*****/www/index.php

which lacks offset information. I am probably on a virtual snipe hunt, but something happened this morning to one of my forum admins and I am trying to run it down while the digital trail is still warm.

We are located in Orlando, FL which is the EST5EDT or US/NewYork or US/Eastern time zone.

Florida starts Daylight Saving Time on
Sunday March 10, 2019 at 2:00 AM local time.

Central Time Zone in Florida is GMT/UTC - 6h during Standard Time
Central Time Zone in Florida is is GMT/UTC - 5h during Daylight Saving Time

For clarity, does the FQ server time stamp *ever* change relative to GMT because of things like Daylight Savings Time?

Sorry, missed the follow up question...

Yes, we are using the official time zone file that is local to us. That means it conforms to both POSIX rules and US daylight saving time laws.
