There is no virtue in onelinedness if the code is unclear and/or
incorrect.

Problems:
(1) Converting UTC time to local time and back again??

  > import time
  You are in a maze of twisty little functions, all alike.

So it can pay to do things a step at a time, and leave a note of your
intentions at each step.

(2) Consider grabbing the "current time" once instead of each for each
file

(3) asctime ... you are missing (an_argument)

import os, time, sys

def buildList(directory):
    listing = os.listdir(directory)
    now_utc_secs = time.time()
    for x in os.listdir(directory):
        x = os.path.join(directory, x)
        if os.path.isdir(x):
            print ('dir -> %s') % x
        elif os.path.isfile(x):
            mtime_utc_secs = os.path.getmtime(x)
            if now_utc_secs - mtime_utc_secs <= 3600.0:
                nSize = os.path.getsize(x)
                mtime_local_tuple = time.localtime(mtime_utc_secs)
                mtime_local_text = time.asctime(mtime_local_tuple)
                print ('fil -> %s %d @ %s') % (x, nSize,
mtime_local_text)

tstN = time.localtime()
print tstN
print "Time now: %s" % time.asctime(tstN)
buildList(sys.argv[1])
