$time = timelocal($t[2], $t[1], $t[0], $d[1], $m, $d[2]);

print "$time\n";usage :

Thank,

Are you passing one or two arguments to the script? You only mention YYYYMMDD but your code appears to be expecting two arguments:

Code:
my $d = $ARGV[0];
my $t = $ARGV[1];


Assuming two arguments, see if this helps:

Code:
use Time::Local;

my $d = $ARGV[0];
my $t = $ARGV[1];
my ($y, $m, $d) = unpack("A4A2A2",$d)
my ($h, $min, $s) = split(/:/,$t);
$time = timelocal($s, $min, $h, $d, $m-1, $y);

print "$time\n";usage :

wmsun

WMSUN(1)						      General Commands Manual							  WMSUN(1)

NAME

       WMSUN - Dockable WindowMaker SunRise/SunSet App

SYNOPSIS

       wmSun [-h] [-display <Display>] [-lat <Latitude>] [-lon <Longitude>] [-td <TimeDiff>] [-date <yyyymmdd>]

DESCRIPTION

       wmSun displays the current day's Sun Rise and Set Times. You must enter your LAtitude and Longitude correctly for it to work.

OPTIONS

       -h     Display list of command-line options.

       -display <display>
	      Use an alternate X Display.

       -lat <Latitude>
	      Set latitude of observer.

       -lon <Longitude>
	      Set longitude of observer.

       -td <UT - LT>
	      Set  the	difference  beteeen  UT and LT. Useful when you want to show the Sunrise/Sunset at a remote lat/lon without resetting your
	      clock.

       -date <yyyymmdd>
	      Set the date to show sunrise/sunset for.

EXAMPLES

       wmSun -lon 106.3 -lat 35.9
	      this would display rise/set times at Los Alamos in local time.

       wmSun -lat 19.58 -lon 155.92 -td 10
	      this would display rise/set times in Kona, Hawaii in local time (in winter -- you need to take  into  account  daylight  savings	at
	      other times of the year).

BUGS

       Who knows? (Let me know if you find any).
