This is, of course, exactly the wrong way to solve this problem.
Perl has date facilities built in -- so *use them*! :-)
$ perl -le '$now = scalar localtime time ; print $now'
Tue Mar 8 11:50:47 2005
$ date
Tue Mar 8 11:50:48 EST 2005
$
So, by default, you don't get the time zone the way the `date` command
does, but if you need that, it's not hard to extract.
See --
perldoc -f time
perldoc -f localtime
-- for details on the built in time handling functions.
If you want to get fancier, CPAN modules like Time::Local, Date::Calc,
etc.
http://search.cpan.org/~jhi/perl-5.8.0/lib/Time/Local.pm
http://search.cpan.org/~stbey/Date-Calc-5.4/Calc.pod
And so on.
There's a lot of thing that can be legitimately done by calling out to a
system command, but getting the date isn't really one of them :-)
