I was aware of that, but with three partitions you won't know on which it 
is and which hash letter was used (we are using fulldirhash as well).

That's great! I wish I had known that before :-)

That's another great tip!

I'm note really a dc fiend, so I'm not 100% sure what you are doing there, 
but doesn't this work just as well?

% perl -e 'print scalar localtime(hex "487BF841")."\n"'

The difference in time is only because of our different timezones ...

Thanks for all the help, Sebastian
