How to easily append (in shell script) a timestamp to tar archive name ?

I would like to create a tar archive with the well known tar command

tar czvf "/usr/local/user234/bkp.tar.gz" /home/users/pmiller/

It works. However I would like to automatically append a timestamp whenever I call this command
in a shell script.

The created archive file name should look like

bkp-20071109-1523.tar.gz

Where the format is preferred as YYYYMMDD-HHMM

Does (Gnu-)tar offer such an automatic timestamp appending?

If not: Is there a (short) work around (in bash) which let me create such a timestamp?

Thank you
Matthew
