remote (ange-ftp) file date and time and UTC

[Kin Cho]

I'm writing some elisp to compare the modification time of a file
and the remote version of the same.

At "Mon Feb 24 10:20:33 PST 2003", I wrote a file
"/kin@foobar.com:/jj".  The dired buffer shows this:

  -rw-r--r--   1 kin      foobar          2 Feb 24 18:20 jj

and (decode-time (nth 5 (file-attributes "/kin@foobar.com:/jj")))
shows this:

(33 20 2 24 2 2003 1 nil -28800)

I have a couple of problems with the above.

First, seems to me zone should be zero, because "date -u" tells
me: Mon Feb 24 18:20:35 UTC 2003

Second, I don't understand hour is 2.  Perhaps it's related to
the wrong zone info.

p.s. my (current-time-zone) is (-28800 "PST")
