I think I am losing my mind. I have some time zone converting code, and I
just don't understand what I am seeing. Also my system seems to return the
wrong time after I do some date operations on unrelated objects.

This is from a machine that is in eastern time. I want to convert to, for
example central time:

$ndate = new Date(date("Y-m-d H:i:s"));
echo $ndate->format("%Y-%m-%d %H:%M:%S");
2013-03-28 15:35:07  <- this is the correct time

echo $ndate->format("%Y-%m-%d %H:%M:%S");
2013-03-28 15:35:07 <- still correct

echo $ndate->format("%Y-%m-%d %H:%M:%S");
2013-03-28 10:35:07 <- this is wrong it should be 14:35:07

$xdate = new Date(date("Y-m-d H:i:s"));
echo $xdate->format("%Y-%m-%d %H:%M:%S");
2013-03-28 19:35:07 <- HUH? This is wrong - should be 15:35:07

What in the world is going on here?

I found this function a while back when I was converting UTC to EST... simple 
task I know, but still...

( I am sorry to whomever wrote this, I didn't keep the source where I found it )

function convert_time_zone($date_time, $from_tz = 'UTC', $to_tz = 
         $time_object = new DateTime($date_time, new DateTimeZone($from_tz));
         $time_object->setTimezone(new DateTimeZone($to_tz));
         return $time_object->format('Y-m-d H:i:s');

I don't seem to have the DateTime object. We are running 5.1.6 and
that was added in 5.2.0. We are getting the Date module from an
external extension. I'll have to see about upgrading.

Well, if you're getting the Date class from a custom extension, then we can't help you. Simply because we have no clue what the extension's code is.

Also, please ask your host to upgrade, 5.1.6 is hopelessly outdated (and unsupported!). The current version is 5.4 with 5.5 coming out very very soon.
