Just to elaborate on what you're doing wrong, when you use the /g modifier on regular expression matches as in:

$stamp=~/\d{9,10}/g;

you need to use a while loop to iterate through all the matches like this: 

while ($stamp =~ /\d{9,10}/g) {
    ...
}

Besides executing your code for every match, this will also make your code work correctly in the case when there are no timestamps in the input line. This is why you are getting the uninitialized value errors and the spurious '12/31/1969' output. You are using $& in localtime and elsewhere even when the line doesn't contain any timestamps.
