# This puts the output from date function in $date.
# Be sure to use backticks!
$date = `date`;

# Print result to output.txt
open (OUTPUT, ">output.txt") or die "can not open file: $!";
print OUTPUT $date;
close OUTPUT;

and if you're specifically interested in `ls` and `date`,
it would be faster and more portable to use the built in readdir and localtime functions.
