Oh, I found a much cleaner solution:
class MyLogFormatter<Logger::Formatter
    MyLogFormat      =      "[%s] %5s -- %s: %s\n"
    def call severity,time,progname,msg
      MyLogFormat % [format_datetime(time), severity, progname, 
msg2str(msg)]
    end
  end
logger.formatter=MyLogFormatter.new
logger.formatter.datetime_format="%Y%m%d %H:%M:%S"

It's not exactly documented (at least the RDoc in ruby-doc stil contains 
the comment about having to hack the Format constant). This way you can 
play with the format constant used and not mess with the logger internals.
Cheers,
