Well, you should specify that you want to print scalar, you're missing the " $ ", the following example works OK :

Code:
#!/usr/bin/perl

print `date +\%y\%m\%d.\%H\%M`;
print "\nthis is separator print statement\n";

$x = `date +\%y\%m\%d.\%H\%M`;
print "$x\n";
print "\nthis is the second separator print statement\n\n";

If you want to capture system command's output, you should not use system(), as it only returns the status of wait(). Use backticks instead as shown above.
