FTP Showing Wrong Time At Servers?

Warning: the following descriptions involve time travel - you may or may not go cross-eyed. This gets complicated, so follow closely.Windows (7, 64bit, build 7600) Explorer is showing a -6 hour difference in time from my actual file date. This is NOT simply the time difference between my computer (in Central time zone) and the server (on Eastern time). Explorer is ignoring the server's time stamp and subtracting exactly 6 hours from the time of the what the server should say. I know this because I'm also looking at the exact same folder and files using XP and the time stamps are exactly as they should be. I modified a file locally (on Windows 7) and copied it up to the server. The time stamp local is 9:36a. The time stamp on the server should be 10:36a, but instead it says 4:36a. So, I copied a file from the server back to here and it reports locally 6 hours later (10:38a) than what is on the server (4:38a). Looking at the exact same files through explorer on XP shows that the time should have been 10:38a.

If it wasn't for time showing correctly on XP, I'd assume it was a problem at the server, but there seems to be something in either the display of time, or in the way it sends the file's time-stamp.And now I'm testing it on another ftp server, which I think has their time set to UTC (my 10:00a is their 4:00p). Using XP, I create a brand new file locally, and transmit it to this server. It initially appears with the same timestamp as the original file (10:16a). I then do a refresh of the server list (in XP) and it jumps forward 6 hours (4:16p). I look at this server with Windows 7 and it shows that the file has a timestamp of 10:16a. So I copy that file (using Windows 7) to its local drive and it tells me that the timestamp is 4:16p (later today).
