Ed, 
   Here is something similar to what Steve Green sent, but is a bit simpler
and accepts a second argument specifying the timezone offset from the
current time zone.  This is handy when trying to understand a log sequence
from a datacenter on a different coast or what have you.

Mark

#!/usr/contrib/bin/perl

$nargs=@ARGV;
$correction = 0;
$x = localtime($ARGV[0]);
if ($nargs == 2)
{
    $offset = $ARGV[1];
    $correction = $offset * 3600;
}
$y = localtime($ARGV[0]+$correction);

print "$ARGV[0] converts to $x (localtime($ARGV[0]))\n";
print "$ARGV[0] with the correction is $y\n";

To convert epoch (unix time) to standard time:

#!/usr/local/bin/perl
## Syntax: <scriptname> unix_time
use Time::Local;
$EPOCH = ($ARGV[0] > 0) ? $ARGV[0] : 0;
($sec, $min, $hr, $day, $mon, $yr, $wday) = localtime($EPOCH);
printf "unix time: $EPOCH ; std time: %02d/%02d/%04d %02d:%02d:%02d\n", 
        $mon+1,$day,$yr+1900,$hr,$min,$sec;

To convert standard time to epoch:

#!/usr/local/bin/perl
## Syntax: <scriptname> mm/dd/yy[yy] hh:mm:ss
use Time::Local;
($hr, $min, $sec) = split(/:/, $ARGV[1]);
($mon, $day, $yr) = split(/\//, $ARGV[0]);
$yr -= 100  if (length($yr) eq 4);
$yr += 1900 if (length($yr) le 1900);
$EPOCH = timelocal($sec, $min, $hr, $day, ($mon-1), $yr+100);
printf "unix time: $EPOCH ; std time: $ARGV[0] $ARGV[1]\n";
