I was surprised that Perl does not have a convenient oneliner to get a timestamp fast enough, such as Ruby has. Nonetheless I did not give up and researched a bit to come up with the following:
my @now = localtime; sprintf("%d%02d%02d",$now+1900,$now+1,$now);
This outputs something like “20091006”.
Though this is a two-liner, it is best I have found this far.

Use strftime !!!
But one would first need include the POSIX module, which would make it still a two-liner with the overhead of module loading.
If POSIX is already loaded, then of course
strftimewould be shorter.
