ange-ftp: coping with broken ls -lt

[Kin Cho]

Hi,

An ftp server that I access using ange-ftp was upgraded and now
it won't support sort by date with "ls -lt" anymore (it always
sort the listing by name).

Sorting by date in ange-ftp dired is such an important feature to
me that I'm considering sorting the ls output in elisp (in my
dired-after-readin-hook function).

I have two questions:

1) have anyone done this?  2) if not, what functions would you
recommend for decoding the dates in the ls listing?  I've
included a sample below for reference:

  -rw-r--r--   1 kin      kin         28705 Jul  7 00:56 foo
  -rw-r--r--   1 kin      kin          9644 Sep  6 05:20 bar

Thanks!
