Usefulness of a script that creates a random directory, puts it in the clipboard, and types it out

Do you ever find yourself having to frequently create empty throwaway directories on your computer? I do this quite a bit, and found it helpful to write a script to (1) create a directory named after the current timestamp (2) put the directory name in the clipboard (3) type the directory name. I just type randdir`, and it is immediately replaced by something like c:\junk\20090612-104031.

I used AutoHotKey to do this, but it could probably be easily done using Apple Automator or any scripting tool.

::randdir::

FormatTime, JA_DirName,, yyyyMMdd-HHmmss

Clipboard = c:\junk\%JA_DirName%

FileCreateDir, %Clipboard%

Send ^v

return
