ok, so i thought this worked, but the test is always passing, no matter what the time is. I tested it by making the "timenow" variable 4 hours from the current time and it doesnt' fail like it should. It shoud fail if it's off by more than 2 hours. Here's my script right now, what exactly is that "if" line saying? and how do i change it to what i want:
timenow=20060907150000 # Your unix time
timeweb=20060907160000 # The time you got from the web
timediff=020000 # your 2 hour difference
if [ $timeweb -le `expr $timenow + $ timediff` ] || [ $timeweb -ge `expr $timenow - $timediff` ]
then
echo "Its a GOOD time :-)"
else
echo "Its a BAD time!"
fi

touch - Sets access and modification time of file
SYNOPSIS
bool touch (string $filename, [int $time = time()], [int $atime])
DESCRIPTION
Attempts to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the
access time is always modified, regardless of the number of parameters.
If the file does not exist, it will be created.
PARAMETERS
o $filename
- The name of the file being touched.
o $time
- The touch time. If $time is not supplied, the current system time is used.
o $atime
- If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the
$time parameter. If neither are present, the current system time is used.
RETURN VALUES
Returns TRUE on success or FALSE on failure.

$time = time() - 3600;
// Touch the file
if (!touch('some_file.txt', $time)) {
echo 'Whoops, something went wrong...';
} else {
echo 'Touched file with success';
}
?>
NOTES
Note
Note that time resolution may differ from one file system to another.
